Ugh, project merge was a bust. Of 27 chicks (9 weeks), I put 5 in the small 5 hen, 1 rooster coop and 3 of those hens were so aggressive, the chicks could never come out of the coop to eat or drink. Sunday night, they were in the rafters as the hens wouldn't even let them roost anymore. The other 22 chicks were in the bigger coop with 26 hens/1 rooster group and they were ok. So, last night, I put the bitchy hens back in the big coop and moved all of the chicks to the small coop with the rooster. He's really good with the little ones and the rooster in the big coop beats his butt. I think I'll just keep them separate like this until the chicks are closer to 18-20 weeks, then get them separated/merged again.
