I am having difficulties with getting my 1st existing flock of 10 to accept the new 7 hens. I have kept them separated and then cooped up at night together. I have left them all out roaming together, but they still don't really get along together. The first 10 hens will not let the newer hens out of the coop. I find this quite interesting since now the weather is changing but the existing 10 remain outside in the weather but keep the new ones stuck in the coop where it is warm and dry. The problem that I am having mostly is that I want to insure that the newer hens get enough to drink or to eat. Since the weather is getting colder, I am told that I should not keep water in the coop as it will add too much moisture to the coop. Our coop is not insulated other than straw bales on the outside walls. Does anyone have any other suggestions or ideas that we could try?
