I have 5 Barred Rocks, 4 Buff Orpingtons, 3 Leghorns and 2 Black Australorps. The Barred Rocks have been living in a different run than the other birds. They are seperated by fence so they can see one another and they also all free range together some each day. My husband built them an awesome 10x12 indoor coop with electricity, Windows, insulated, 6 nice nesting boxes and several roosting bars. I want to integrate the two flocks before it gets cold so they have a nice place to stay warm. I put the 5 Barred Rocks in there first then added the 3 leghorns. They seem to have adjusted well except that 2 of my Barred Rocks have turned out to be Roos, 1 who wants to service every girl in sight now while the other is much more docile. Yesterday I added two of the Buff Orpingtons and again, everyone seemed fine. Today when they were all free ranging I noticed that my other two BO's didn't seem to be acting like their normal selves. They acted like maybe they were getting sick. My question is could they just be depressed because I seperated them from the other two BO's. I started to put them in tonight but didn't because I am just not sure if they are sick or just lonely. The two Austrlorps they are in with are definitely the most aggressive of the hens but they have been together since I got them. They are all about 22 weeks. Advice would be great!! Also, is it ok to keep both Roo's and is it normal for him to be servicing all the hens? Does this upset the hens?
