Will his apparent recessive white gene ever show up in his offspring?

Also, yeah, that is an oddity.

17 pounds?
That's the biggest rooster I've ever heard of?

Did your white hen have any black spots?

17 lbs is the biggest I’ve ever heard of too! He’s 12 lbs twelve.
The mother? No solid white even as a chick. The baby? Yes the was mostly white at hatch with mixes of black.

Nope, I read hens can retain sperm for up to 5 weeks, that much I already knew. The only other active rooster I had is a 17lb Wyandotte mix. He was indoors, up until 5 weeks ago or so. (It’s a long story, he’s special, I’ll leave it at that). So this is an oddity? I’m not crazy right?

17 pounds? Holy Cow! Yeah, he’d crush a bantam

12 pounds. 12. Hrs still too big for my 14 oz bantam. But 12. Is there a way to edit posts? Either I hit the wrong button or autocorrect puts craziness.

Yes there is.

Yes there is, click the three dots on your old post.
Okay my verdict is this, given the information I have. Dominant White must exist in Recessive White Cochins. Crossed with other colors, maybe you'd get some dominant whites that carry recessive white but just look sold white. And that hen had a copy of dominant white. That's the only explanation I can think of.

This puzzles me and i'd love to hear the conclusion.

My best guess is one bird is dominant white + black (and may not be purebred if there is no dominant white cochin as Amer said) and the other is recessive white+recessive white, which should still give you a 50-50 chance of a white offsping. If this is true, you might see a single black/colored feather on either of the white birds to figure out which of them may have the dominant white gene (because it is "leaky" so colors sometimes bleed through here and there).

If you want offspring with both recessive white genes, I'd still breed father to daughter as that is your best bet: the black cochin hen must have a recessive white gene and you only have one white rooster. I may be mistaken but that should give you 3/4 white offspring (if the rooster is white-white and the hen is black-white) or 50/50 if the rooster has the dominant white gene and not two recessive ones.

If one of the birds had recessive white+dominant white and the other dominant white/block, you'd get 3/4 white offspring from the two white birds pair.

I guess the only way to know more would be to hatch more chicks from the white pair and parent to children from that pair to see what you get.

Sorry if this is off topic, but I have a recessive white chicken with one black feather that has grown in (the bird is 4.5 months) It has me baffled. There is no way the bird can be dominant white as neither parent has a dominant white gene.

Recessive white can have off color feathers. I've got no explanation that's just how it is.

Oh thank you so much! I hadn’t ever heard of that, and I thought I was going crazy!

That said recessive whites can carry dominant white but I just took you at your word that he is recessive white.
