I have a few adult hens and two roosters. I also have about 13 eight week old chicks that are in another see through section of the coop with the adults. They have had a lot of time to get use to each other but when I let them out they get pecked real bad and Im afraid to let them out completely because of the two roosters too. How do I do this without a little ones getting killed or beat up? A couple of the little ones are roosters too but I will be selling them soon. The adults peck all of them not just the roosters.
