My chickens are pasture free, they only go in the chicken house to sleep and lay eggs.I I have had many people wanting to buy my eggs but do not have enough to go around. That being said how many chickens can I house in a 8 foot by 8 foot by 7 feet high and I have 6 nesting boxes and approx 20 or so linear feet of perching area. I want them to be comfortable but I would like to know how many I can fit in there comfortably before building another chicken coop. I have 12 chickens in there now, I am adding about 25 more in April. Thanks for your help.
