🏠 Recommended Coop Size
0 sq ft
🐔 Space guidelines: Standard recommendation: 3-4 sq ft per chicken inside coop, 8-10 sq ft per chicken in run. Larger breeds (Brahma, Jersey Giant) need more space.
💡 Pro tip: Build bigger than minimum — more space reduces stress, pecking, and disease. Include roosting bars (8-12 inches per bird) and nesting boxes (1 per 3-4 hens).
