it is possible but will take 3 years of selective breeding to breed it out ,so does not worth th effort .
chooks man
thank you.
I have just check her again. the rest of her skin is white/pink and her feet are not as yellow as plymouth rock or similar. her feet look like 75% yellow. I looked at the bottom of her feet and there is mostly pale yellow with pink batches. she looks solid black (I will try to breed solid black/blue/splash). in case she has a nice straight comb I will use her. my pain is to find a hen with straight comb.
I lost the cockerel that was my hope to build a new, better bcm line. I am thinking to use dark cuckoo roos with solid black and blue hens and create solid black/blue/splash marans.
