Frequently Asked Questions
How much coop space does one chicken need?
Standard breeds need about 3-4 square feet of coop floor space per bird, while bantams need less (around 2 sq ft) and large heavy breeds need more (around 4 sq ft).
How much run space is required?
A general rule is 8-10 square feet of outdoor run space per standard-size chicken, though this can be reduced if the birds get substantial free-range time.
How many nesting boxes do I need?
Generally one nesting box per 3-4 hens is sufficient since hens will share and take turns using boxes throughout the day.
