I have 10 Rhode Island Red chicks that are about 10-12 weeks old. I am keeping them in a small coop inside the hen house. They are not fully feathered out. In the hen house I have 8 other chickens. Since one started crowing this week, I know one is a cockerell (W. Leghorn and he seems to be nice.) I think they are about 3 months? I don't know. I was thinking about letting out the little RIR hens, but I'm weary now that I have a cockerell on my hands. I would like suggestions when I can let the little RIR's out of the coop to join all the others. I would be sooooo sad if they got pecked to death.
