Cochin and Wyandote Cross

[Avisius]

Hi,

I have this 11 weeks rooster.
I'm thinking it's a silver laced / white columbian mix between a Cochin and a Wyandotte. I have other various mixes between different colors of cochins and that's why I suspect it's partially a cochin.
Or maybe Brahma and Wyandotte.
I'm not sure what kind of comb would reusult from such mixes.
What do you think?
Does anyone have such mixes?
Do you have any photos of Wyandotte X Cochin/Brahma?
Thanks.

Well in theory, Wyandotte x Cochin would produce rose, and Wyandotte x Brahma would depend on what the parent were homo/heterozygous for.

Basically the two major comb genes are rose and pea. If either of these dominant genes is present and the other is not, that's what comb type it gets. If neither is present a chicken will have a single comb. If both are present they'll have a Walnut comb. Then there smoothing factor and other such complications that modify the comb. But in theory a Brahma Wyandotte cross would have Walnut/cushion if both parents were heterozygous for their combs and passed it on to the chick

Thank you. Very interesting.
And does the comb look like an incipient walnut or a rose?
Or is it too undeveloped and the picture too unclear to determine?
Until this fella, all my chicken were either with pea comb or with single comb, so I didn't have the chance to see other examples. I've searched for some images of young Wyandotte cockerels and their comb seems to be bigger and not as smooth. But probably it's because they have the stronger gene, the RRpp.

Here's a good look at the combs https://www.backyardchickens.com/articles/the-9-comb-types.63029/

Looks like a rose comb to me
