I aquired a laying hen and what was supposed to be 2 of her pullets. They were about 6 wks old at the time. Well, I'm pretty sure on of those pullets is a roo. I do want to raise chicks, but would it be acceptable for him to father chicks by his mother? Seems awful weird to me, but maybe chikckens are different. The "pullets" are between 5 and 6 months old now.
