i have a lovely new 4x8 coop not including the nesting boxes on both ends. I plan on putting my 8 chicks in there once feathered. i keep reading about folks getting addicted to buying chickens and ending up with 20+ before they know it. Do you keep building bigger coops, adding on other coops, or are some of you cramming more in the coops than the recommended 4 sq ft per bird? How big is your coop if you have over 20 birds? Just curious, not judgmental. New to chickens.
