I just put 2 new 1 yr old br's in with my flock of 10- 3 yr olds last nite while they were all roosting. this morning i watched and excet for a little pecking everyone seems fine. I have rr's, bo's, sex links and 1 other barred rock. 1 of the new br's is pretty fiesty and when pecked by the adult br, she pecked back and they did a little chest butting. I also let my older hens out to free range in the afternoon. should i keep the 2 new ones in the coop for a couple days, or longer while the others are out? I am hoping they will follow the others after a few days. today they were happy to be in the coop by themselves to eat and drink in peace. the fiesty one has no problem, but the other is scared to come off her roost when the others are there. I am afraid if rains start up i will need to keep the coop open so the others can run back in during a downpour, which is what they do.
