Ok,, I only have six chickens total. Two Barred Rocks a little over 2 years old, and four new ones that are about 4 months old. We are going to be getting some cold weather here the next few nights, and I wanted to get the new chicks into the coop with the older ones for warmth. I have kept them apart, letting them see each other through the fencing. Yesterday, I put the older hens in with the chicks one at a time for a while. Then with both the hens, in the enclosure I have made for the new chicks. The older hens pretty much ignored the new chicks, but, the new chicks are scared of the hens. They group together in the corner. The older hens if given a chance, do peck at the chicks, not hard, but just being "bossy"... How long before they are ok to be together without my being there to supervise? They were in the same enclosure last night, the hens in the coop and the chicks roosting on a branch in the corner of the run. I want to be able to put the chicks in the coop at night. I think, in retrospect, I should have put the new chicks in the coop and run area, and moved the hens to the new enlosure. Will the older hens hurt the younger ones, or am I being a worry wart? I realize they have to establish a new pecking order, and that they will do it on their own schedule. I feel like such a ninny!!
