Coops & Sizing
Every coop guide on this site runs the same check: the maker's bird claim, against published floor dimensions, at 4 sq ft of interior floor per standard bird. This page collects the results — the flock-size guides, the cold-climate picks, the re-rating dataset and the sizing standard they all share. Start with your flock size, or grade any coop yourself with the capacity checker.
