This spring I bought 2 Delaware breeder hens and a rooster from a local breeder who is now shutting down business. He no longer sells Delaware chickens, so I'm thinking it is going to be important that I get another rooster so that I can keep my Delawares going. I've done research, and realize that it is ok to breed daughters back to fathers and sons back to mothers. Here is what I am thinking about doing, and I am wondering if this would be a problem. I am considering separating my original 2 hens from the rest of the babies they have produced along with one of their sons. I will put the rest of the hens with my original rooster (their father). I will keep these two flocks separated. Now, later if I need to replace either one of my roosters, would it be safe to take from the opposite flock and breed back to the offspring I will be getting from the flock in which the rooster needs to be replace? I hope this makes sense... Group A Group B Rooster (father to all) Rooster (Son of the hens below and the rooster of Group A) Hens (daughters to rooster above and Hens (mothers to rooster above and hens in Group A) hens in Group B) If I need a new rooster, I would take from A and put with B or vice versa.
