I have eight four week old chicks. I am in the process of putting them into a small coop I have outside now that they have most of their feathers and it has not gotten real cold yet here in the South. My questions is, does it really work to sneak the new chickens in with the existing hens at night and sit them on the roost with the older chickens in the main coop? Want to come up with a solution to try to avoid too much stress and pecking going on with new chicks. They will be free ranging with older chickens for awhile before we start the integrating process. Thought I would wait till they are about 3 months old before I try to put them in coop with older hens.
