I was wondering about the same issue. I have two four year old hens and 8 new babes that are currently 7 weeks old. Would it be ok to let them into the same coop and run? The older girls free range during the day now and was not sure if I could put the youngsters out with them. I would not want the little ones to free range yet, as I would prefer them to be full grown. Is this a good idea?
Any input would be appreciated.
