none of the parents have split wing. Buster has half brother who does have split wing and hens have a half brother who also has split wing(my other cock bird). Assuming you are right on with all parents being recessive carries which gave me 100% split wing chicks on first hatch. Is it possible to hatch “non-split wing” from this trio? I am thinking not.
both parents are recessive . yes it is possible to get normal wing chicks , you just have to hatch more chicks and cull early . you will still have normal chicks but will be carriers ,that is a problem in a long run .
only test mating and hatching more chicks ,cull early can fix this type of problem .
