This might me a dumb question, however, I am brand new to chickens and still learning i would like about 20 hens.... And a few roos. Seeing how chicks are generally half Roos and half hens, that means that I would need to get about 40 chicks. I am going to build a henhouse that is 90+ sq ft (4sq ft per bird). I am curious if I should be concerned about overcrowding while I am letting my birds age enough in order to take the extra roos for the table/freezer. I want to be able to eat the extra Roos but want them big enough first. Any explanations and advice is very appreciated thanks!!!
