I have had two roosters and it's been great. But....they just hit puberty! So far there doesn't seem to be any fighting but one of the roosters stays inside the run and refuses to come out. The other "herds" his girls outside in the run. What can I expect in the future? We currently only have 4 hens since we had a predator last fall. Do you think if I get more hens there will be more to go around and the 2nd rooster will not feel so intimidated?
