So, I have 24 chickens, which are about 12 weeks old. Currently they are in a 4x8 plywood box, with a hardware cloth top. Obviously, they are outgrowing their present home, and our coop needs to be finished ASAP! DH and father are going to be building it over the next couple of weeks. Our plans will be similar to the "Wichita Coop" shown in the "medium sized coops" only bigger. The enclosed run portion (including the section under the "coop box" will be 8x12, for 96 sq. feet of outdoor space. The inside of the coop will be 6x8 for 48 sq. feet of indoor space for roosting, and nest boxes. We are planning on thinning our flock by half, come spring (once they are laying) but I would like to pick up 3 more chickens (a rooster and 2 hens of a different breed, which wasn't available when I got my chicks back in October) to add to the current flock. Do my numbers look okay for a flock of ~15 birds? When we finish the coop, should I go ahead and split my flock, and keep half in the current 4x8 box, and move half to the coop, or just move them all to the coop, until spring? Will they be too crowded in there, with half again more space than what they currently have. Also, I know that when chickens are allowed out, you put them in the coop and confine them there for the first couple of weeks, so they know it as home, and will return at night. Since they are going to be in an enclosed, covered run, is that step necessary, or can I move them into the new coop, and immediately give them access to their outdoor run? Right now they are confined to their box, because they are living in the garage, until we get the coop finished. TIA!
