On Monday I put my 24 3 month old chicks with my current flock. They had been living in the same coop but separated by chicken wire for a month. Things are go smoothly, everybody is basically ignoring everybody else, just a peck on the head here and there. I am wondering if I can add the new rooster I got recently. He too is in the coop but seperated by wire, so they can get used to each other. He's been there for about 2 weeks. He SO wants in with the ladies and a couple of them seem interested in him also. If I put him in too, is that new many chickens at once? Everybody has plenty of room: 9.5 feet per plus runs and free ranging.
