Not sure if this is the right area to post, but it is about chicken behaviors. Does anyone know the "rules" when it comes to breeding relatives? Lemme explain why I ask. I have a new Chocolate Orpington bantam cockerel I got last week. Today I picked up a female to match, from the same person. So, since she hatches her own, I am not sure if they are siblings or not. I know not father/daughter because they are a week apart in age. Is it taboo in the chicken world to breed brother/sister or father/daughter? Even if they aren't siblings and her eggs are fertile, I'd like to hatch some...but would I have to start a new flock with them since the roo will be their dad???? LOL, I'm so confused!
