Roosters with hens in a small area = trouble. You will soon have hens with bare back, subject to possible sunburn. They will not regrow feathers until the next molt. As you discovered, there's always an Omega bird. If you remove the current one, a new one will be selected.
I sure hope you can get a large area for them soon or you may end up with non-reversable behavior problems...
Yikes! Yes, the coop is the next project on our to do list. We do have one more rooster that will be removed soon, so hopefully that will help. I had no idea there would be such a learning curve to chickens.
Our poor frizzle is missing feathers but her breed has a genetic condition that makes their feathers more fragile. I hope she recovers. -Aimee
