I have 16 6 week old that are outside in a pen and I am wondering when is a good time to let them free range in the yard with the big ones. I do have 5 roosters that I would like to get rid of first and I am hoping to do that this weekend at the local auction. This morning while I was changing the water in there pen the 11 week old roosters got in there and there really was no trouble. The back side of the main coop is all wooded and I have lost a few already to the woods. Now the big ones stay close to the house and in the shade. I just really don't want to lose any of the hens, for some of them are so cute.
