Yep, I was referring to having a homozygous muffed cock and a clean faced pullet.
If your bird throws clean faced offspring, that's what I was mentioning in the problem with crossing a clean faced to a fully muffed/bearded bird - Although the offspring may seem perfectly fine, . . . They're not. And that's a huge problem with some BBS birds out there. People think that just because they get rid of their clean faced birds, the problem is gone. Well it's not. The thing to do, if not replacing your flock, is to test each bird by breeding for who has only one allele, who doesn't. Takes a lot of chicks to do it properly though.
