Inbreeding question?

[tuesdaylove]

My pullets are likely going to start laying soon, and there's going to be a problem: I'd like to keep some baby chicks (but only the pullets), and when they're grown, won't their fathers try to mate with them? Would it be dangerous if that happened? Like, would the baby chicks be okay if their father was also their grandfather? I can't separate the future babies from the roosters to prevent inbreeding if I keep any chicks, because I only have two chicken pens where my two flocks are already and I don't have room for any more.

Also, when will my pullets start laying? I have three bantams, Cochin, d'uccle, and rosecomb, all at three and a half months old, and a standard bird who's either a White Leghorn/Plymouth Rock/Cornish cross who is four months. The two roos are three and a half months - are they fertile yet?

Any advice is greatly appreciated! I am still very new to chickens and I don't know hardly anything about them.

I usually get a different roo to keep from inbreeding but don't think you should have a problem.

Chickens aren't like people and don't have the moral or social constraints that people do. Having the father over the daughter is a common practice in the animal world. A deer buck will breed 8-10 females for multiple generations, putting his DNA a dominance within the herd. This is typical of many animal species. Father/daughter is a good breeding, and is much preferred to brother/sister matings.
