So I have 2 cream legbars (Rees line) that I obtained from a local breeder, I believe the eggs they hatched from were from a breeding group of 1 rooster with 3-5 hens, so they could be siblings or half-siblings. I was wondering if I could hatch any of the pullet's eggs, or if this would be too risky in terms of deleterious alleles showing up? I find it odd that father-daughter breeding is much more accepted than sibling breeding, even though the relatedness is the same!
