Hello. I apologize if this has been asked before. I couldn't find any information on this specific situation. I have three approximately 2-1/2 month old Orpingtons and thirty-one 4-week-olds. I had intended to keep them separate until the younger chicks caught up in size to the older chicks, but they are quickly outgrowing their section of the coop. Would it be okay to introduce the 4-week-olds since there are so many of them, even though they are much smaller in size? I have no adult chickens. They have been in the same coop, but separated by a wall, so they haven't been able to see each other.
