Provide minimum 4 sq ft of coop floor space per bird

Allow at least 4 sq ft of floor space per standard-sized chicken inside the coop. Bantam breeds can manage with 2-3 sq ft. This is the space where chickens roost at night and shelter during bad weather, so overcrowding directly causes stress, feather picking, aggression, and faster disease spread.

Why It Works

Chickens in overcrowded coops cannot escape dominant birds, leading to bullying and injuries. Tight quarters also concentrate ammonia from droppings, causing respiratory damage. The 4 sq ft minimum gives each bird enough room to move, turn around, and access feed and water without competition.

Tips

• More space is always better — 6-8 sq ft per bird is ideal if your coop allows it
• In cold climates where birds stay indoors more, aim for the higher end of space recommendations
• Calculate usable floor space after subtracting area taken by feeders, waterers, and nesting boxes
