We have made a coop that is 8x8(of floor space) it has 8 perches, 10 nesting boxes. We can add more perches if we need to. The coop is conected to a 10x10 run. My question is how many chickens can it house? We have 27 4 days old chicks now and have a few people that want some. How many should we keep? Also we have 2 acres where they will be able to free range for 1-2 hours a day.
