Fixed A-Frame Coop
A fixed triangular enclosure with a rear shelter and front integrated run. Compare rear and side service approaches while keeping the same footprint. Low edges remain low: a floor-area total does not establish standing room or usable bird space.

Where this arrangement fits
More suitable when
A fixed site where the rear shelter and separate front run can both be serviced from outside.
Choose another direction when
A walk-in maintenance routine, a site with inaccessible low edges, or a request for a movable tractor.
What still needs checking
- Test both lower edges with actual tools; maximum apex height is not height across the whole room.
- Keep the rear shelter/front run division identical in the overall, section and operation plans.
- Service-panel structure, supports, weather details and anchoring require local review.
Keep total size, shelter and run separate
The existing fact card defines a 4 × 8 ft overall envelope with approximate rear and front halves. This study freezes a 48 in division and assumes 2 in wall allowances: 44 × 44 in clear shelter base and a 56 in internal apex. The straight inner slopes, fittings and service panels are new editorial assumptions; the design has no claimed mobility.

Clear base dimensions do not subtract fittings or establish usable bird area. Design-name flock counts are historical planning labels, not a current verified match.
The slope example has about 25.1 in width at 24 in above its assumed base. That cross-section calculation does not establish a welfare threshold or usable floor area.
Materials with a job to do
Work through these five groups before asking for prices. The worksheet leaves purchase quantities open until the design and selected products are resolved.
Base and sloped frame
Define the fixed body and the space beneath the sloping sides.
Split the order by: Base and sloped members: pieces by section and blank length.
What can change this choice
A slope drawn through the assumed section is not a rafter specification. Do not derive saw angles from the concept picture.
Ask for these specifications
Request final member sizes, material grades, ridge/base connections and an identified drawing for sloped cuts; a silhouette is insufficient for quoting cuts.
Establish the quantity
Resolve the actual outside/inside frame, member thickness and shelter/run division before choosing timber.
Check the supplied items
Check supplied sections and blank lengths against the frame schedule. Keep any unconfirmed sloped cut marked pending before machining.
Roof skin and ridge/end closures
Weather the shelter without leaving uninspectable joints at the base or ends.
Split the order by: Roof faces: sheets by effective cover; ridge and end closures: lengths.
What can change this choice
Separate the shelter's weather skin from the front run enclosure; detail their transition explicitly.
Ask for these specifications
Request developed-face coverage, ridge/end profiles, compatible fasteners and weather-junction instructions for the selected roof product.
Establish the quantity
Measure developed roof faces, ridge length, end treatment and selected product overlaps after the frame is fixed.
Check the supplied items
Check both roof-face quantities and the separate ridge/end components. Verify matching profiles instead of accepting visually similar trim.
Side service panels and hold-open hardware
Expose the low floor and allow fittings to leave the shell.
Split the order by: Each service panel: one assembly; hinges, stays and latches: itemized.
What can change this choice
Choose a reviewed hold-open arrangement. An open panel drawn in an illustration does not establish its restraint.
Ask for these specifications
Provide the proposed panel weight and full open position. Request compatible hold-open hardware, attachment requirements and keeper-access dimensions.
Establish the quantity
Record panel weight, hinge location, open sweep and the keeper's standing space.
Check the supplied items
Check handedness, hardware models and included fixings. Confirm the specified backing can be identified on the current panel drawing.
Nests, roosts and removable lining
Arrange equipment within the narrowing cross-section.
Split the order by: Nests and roosts: assemblies or scheduled pieces; lining: removable sections.
What can change this choice
An item can fit on the base and still collide with the roof above. Check the section before the material order.
Ask for these specifications
Request closed, open and removal envelopes for each fitting, including lid height and handles. Compare these with the section at their actual height.
Establish the quantity
Measure at the height of the complete fitting, including a lid, handle or removal lift.
Check the supplied items
Compare the delivered dimensions with the section trial. Identify any changed lid, handle or retainer before fixing it beneath the slope.
Front run mesh and base closure
Connect the open zone to the shelter and ground boundary.
Split the order by: Mesh: rolls or panels; triangular offcuts and edge attachments: separate.
What can change this choice
Keep the fixed design's ground and access details separate from mobile-coop assumptions.
Ask for these specifications
Specify mesh aperture, wire diameter, coating and stock size. Request the chosen edge-attachment components for triangular ends and moving openings.
Establish the quantity
Measure triangular end faces, side faces, openings and overlaps separately.
Check the supplied items
Check the labelled specification and usable stock dimensions. Match edge components to the end-face and opening details before cutting mesh.
Resolve the design in a useful order
A design-development sequence: complete the decisions before turning the reference into construction drawings or an order.
Read the section first
Compare the assumed base width with the narrowing width at the proposed fitting height.
Before continuing: The complete equipment envelope, including opening movement, stays inside the reviewed shell.
Try exterior reach
Make the full-size section trial below and use the intended collection and cleaning tools.
Before continuing: Low corners can be reached without an unsupported panel being used as a platform.
Resolve the shell and panels
Develop the frame, weather skin, service openings and hinge restraints around the chosen arrangement.
Before continuing: Each panel has a closed weather detail and a defined open position.
Coordinate the run and ground
Record the shelter/run connection and all base boundaries before preparing quantities.
Before continuing: The bird route, keeper approach and surface-removal route remain accessible.
Fitting project
Make a full-size slope template
Test the actual nest or container against a section, including the space needed to lift it out.
- Draw the chosen section at full size. If using the study's 44 in base and 56 in apex, label both as assumptions until a final shell is designed.
- Place the full fitting envelope at its planned height. The study's straight-slope width is 44 × (1 − height / 56), with all values in inches.
- Open the lid and trace the lift/removal path. Mark where the object or keeper's hand first meets the slope.
- Adjust the fitting position or access panel and repeat. Transfer the successful arrangement to a final framing design before using it for cuts.
Does the sloping side leave usable reach at fitting height?
Use the section as well as the plan. Mark the actual height and open position of each fitting, then try the keeper’s reach from the service opening. Do not infer occupied space or headroom from the base rectangle.
| Task | Rehearse | Keep in the record |
|---|---|---|
| Fitting at height | Compare its full envelope with the section. | Record the height where the slope first interferes. |
| External service | Try collection and removal with the opening fully open. | Keep the tool and container path visible. |
| Placement | Check the slope-side weather and access conditions. | Compare a vertical-wall form if the job cannot be completed. |
Collect → refill → inspect → remove bedding
Collection and refill
Stand behind the shelter for eggs and inspection; use the front run opening for F and W.
Full clean
Remove assumed lift-out fittings and draw bedding toward the rear opening. Check the far low corners from that position.
Recheck the result
Restore secure fittings, continuous bird access to feed and water, clear keeper access and every enclosure closure before returning birds.
Read the fitting labels with their care tasks
- N · Nest
Check bird approach, egg collection and full lining removal.
Explore n · nest - Roost
Lift-out is an editorial assumption; supports and secure refitting need review.
Explore roost - F · Feed
Reserve refill access without obstructing the gate or bird connection.
Explore f · feed - W · Water
Check spills and continuous bird access after every reset.
Explore w · water - Bedding and base
The supporting floor and replaceable material remain separate decisions.
Explore bedding and base - Protected air
Opening placement is a relationship, not a calculated ventilation rate.

Compare the operation in the same shell
A · Rear-end shelter service
Same-shell operation study · a-frame-editorial-4.2.0
Everyday: Stand behind the shelter for eggs and inspection; use the front run opening for F and W.
Full clean: Remove assumed lift-out fittings and draw bedding toward the rear opening. Check the far low corners from that position.
Trade-off: Two end approaches must remain available; the far shelter edge may be hard to reach.
B · Side shelter service
Same-shell operation study · a-frame-editorial-4.2.0
Everyday: Use an assumed side panel for nests; refill supplies through the same front run approach.
Full clean: Open the reviewed side panel and test removal along the shelter length; remove fittings before reaching below them.
Trade-off: A different reach direction, with additional side clearance and weather-detail review.
Keep the design and decisions together
A six-page companion: current layout, two pages of material specifications and worksheet guidance, a practical project, the preparation sequence and a worked decision example.
In this design
- Outside envelope and slope section
- Two care arrangements
- Full-size fitting trial and material scope
Still to resolve
- Final sloped frame and roof connections
- Service-panel hardware and weather joints
- Quantity-led BOM and member cuts
The published outside envelope is 4 × 8 ft. The current study assumes a 44 in shelter base and 56 in inner apex with straight slopes. These are editorial dimensions, not a released frame or saw-cut template.

Download Fixed A-Frame design workbook PDFTurn the worksheet into a usable request
Use the PDF to understand the design; use the CSV to record products and quantities. A completed description is a request for review, not automatic approval to order.
- Split a group into order lines. The five groups organize the work. Copy a group into separate product rows when sizes, models or purchase units differ; keep its Scope ID on every copied row.
- Keep quantities traceable. Enter quantity and unit together, with the measured sketch or drawing revision and quote reference. Leave an unknown quantity blank and set its review status to Pending details; blank is not zero.
- Reconcile before ordering. Name the exact product and record unresolved substitutions or excluded parts. Record who checked the line and when. Update affected quantities whenever the drawing or product changes.
When the supplied items differ from the agreed specification, record the discrepancy against its Scope ID and resolve it before using them in the assembly. Receipt checks do not establish structural or handling performance.

Use this plan in three moves
What you can take away today.
Start with a measured footprint check, work through the five decisions below, then carry the unresolved parts into a local review. The 14-page Design Sheet v3.1.1 and your browser-only record use the same question structure.
- 01
Measure the fit
Enter one candidate yard rectangle below and test the published footprint in both orientations.
- 02
Resolve five questions
Check flock, site, routine, weather and budget against the supporting Design Sheet pages.
- 03
Carry unknowns forward
Save observations and open questions in a browser-only record for local review.
Measured yard fit · rectangle check
Put the Plan inside a space you measured.
Enter the usable rectangle left after any locally required setbacks or routes you already know about. The result checks two orientations and keeps everything else visible.
Measure one candidate rectangle. Enter decimal feet or field notation such as 10' 6"; the worksheet converts inches for you.
Current readout
Enter both measurements to compare at scale.
1 selected Plan. Positive remaining lengths are unassigned space, not recommended clearance.
3–5 Chicken Fixed A-Frame
Candidate area not measured.
Still measure or confirm
- Keep working room outside both exterior access points; this rectangle does not assign service clearance.
- Observe drainage, lower-perimeter gaps and the short bird route before treating the compact fit as suitable.
Step 02 · Make the plan yours
Five questions to carry from the Design Sheet to your record
You do not need every answer today. Record what you have observed, keep unknowns explicit, and use each page link to see the relevant reference.
FLOCKThe 4 × 8 ft number includes two zones+
The reference includes a rear shelter and front integrated run for a 3–5 chicken planning direction. What birds, breeds and confinement periods must those two zones support?
Keeper: record actual birds and outdoor use. Local Extension: discuss housing conditions that remain unclear.
SITELeave working room outside both access points+
Mark the complete 4 × 8 ft envelope, shelter service approach and separate run-gate approach. Where do rain, low ground and removed bedding meet those routes?
Keeper: observe the site safely. Local authority: confirm use and setbacks. A suitable site professional: assess drainage or support changes.
ROUTINETest the low-edge cleaning posture+
Can you inspect the low nest area, higher roost, shared bird opening and rear bedding zone through exterior service access without an awkward or incomplete clean-out?
Keeper: rehearse the care route with real tools. An experienced keeper or local Extension can help review reach and cleaning conflicts.
WEATHERReview the base, roof edges and high air path+
What remains unknown about drainage, support, anchoring, wind, snow, roof runoff, protected high ventilation and gaps at the lower mesh perimeter?
Keeper: record exposure and openings. A qualified local professional: review proposed support, roof, anchoring or structural changes.
BUDGETPrice the entire compact envelope+
Which base, weather skin, mesh, two access systems, care fittings, site work and recurring maintenance costs still need a local quote or clearer scope?
Keeper: list the whole scope and unknowns. Suppliers: provide dated quotes. Appropriate local professionals: define site-specific work.
Step 03 · Keep the evidence with the decision
