Hi!
Welcome to BYC!
I've read that you need 4sf per chicken in the coop...double or triple that. I've also read that you need 10sf per chicken in the run...double or trible that. Why? Because, chicken math.
Plus, I just think they are happy with lots of space. I keep a flock of around 12 chickens and have approx 4,000sf of run space. They love it! But, because I didn't know about chicken math, I have 3 coops, and now this spring DH will be building one big new one.
