Very nice coop!Mine is limited to 4 hens, I have 2. And the coop is limited to 120 square feet... Which could equal a 10' x 12' area, I think. Not sure how to calculate it for a coop. It can't be any taller than 7' high and must be 6' away from any property lines. I bought my coop from www.chickensaloon.com. I got 'The Saloon'. They are pretty expensive, but so easy to put together, high, high quality, and perfect size for my 2 girls.Also, Longmont doesn't allow free ranging unless all neighbors give u written consent.
