Help!! I want to breed pure Hubbards...I have a Hubbard rooster and a Hubbard hen. I have noticed that my Hubbard rooster only mates with another breed, my native chicken who is smaller than him BUT he does not breed with the Hubbard hen (as far as I know). How do I make him breed with the Hubbard hen? Do I need to isolate the pair? Any suggestion?
