Coop plans / capacity
Start with 12 birds and their outdoor-access condition, then compare usable space and the daily-care route. A flock label does not require one particular coop style.
Direct answer / source conditions first
There is no single number independent of the housing system. These are published Extension starting points multiplied by 12, not a construction specification or a capacity approval for a particular Plan.
| Source and condition | Indoor starting point | Outdoor relationship |
|---|---|---|
| OSU — outdoor access available | 36 sq ft inside 12 × 3 sq ft / bird | Assumes access to an outdoor run. This indoor allowance does not size the run. |
| OSU — no outdoor access | 96–120 sq ft inside 12 × 8–10 sq ft / bird | More space indoors when birds lack outdoor access; do not substitute the run-access number. |
| Penn State — laying-hen housing table | 18 sq ft inside 12 × 1.5 sq ft / laying hen | 96 sq ft outside (12 × 8). This is a different source and housing context, not a reason to select whichever number is smallest. |
Source conditions must be reviewed alongside breed, bird size, confinement time, ventilation, management and usable floor area. Guidance is not a local building or animal-keeping rule. Our Plan facts remain separate and unchanged.
These are reference directions, not a verified usable-space or site-fit test. Open each reference for its actual enclosed and outdoor relationship. Flock size alone does not select a style.
These are comparison references, not verified matches for 12 birds. None currently has reviewed flock suitability. Use the source conditions above, actual usable indoor area, outdoor access and confinement to assess fit. A larger name or total footprint does not establish capacity.
Walk-in · suitability needs review
A central aisle and room to compare storage
Trade-off: Storage reserves reduce the remaining floor.
Run: Separate outdoor run
What this comparison resolves: Compare the storage reserve with the remaining floor and full-clean route.

Separate entrances for coop and run
Trade-off: Rear roosts interrupt the front working lane.
Run: Included covered run · 6 × 8 ft
What this comparison resolves: The enclosed coop, separate run and total body are three different area figures.

An attached sheltered outdoor zone
Trade-off: Enclosed coop is only part of the total footprint.
Run: Included covered run · 6 × 6 ft
What this comparison resolves: External service needs a reachable far corner and a workable supply/removal route.
