So, I'm trying to get partridge hens from my partridge rooster and black hen (they are bantam cochins, I know the breed shouldn't matter for the most part, but just saying what they were). I know I would have black with gold leakage in F1, and if I bred back to dad the F2 would be partridges and partridges with melanizers, but that isn't what I'm asking. I'm asking if would it be okay to bred the F2 back to their grandfather/dad, or would this be to much inbreeding?
