Ok 8 days ago I found a chicken wondering around my yard. My neighbor had the day before gotten some free range chickens and said we could keep it. Which was nice of them. Any ways I have not let it out of the coop to run with my other chickens since. They seem to get along most of the time. Still some pecking, which is mild and normal. My question is does any one know how long I should keep her, little red, in the coop before letting her out to run with the others? Here is a pic of her. Not sure of the breed. Thnking she is a red sexlink. Thank you for any help.
