That's very interesting. I've never been in a position to do those crosses myself, so I was guessing from what I've been able to find online. It's nice to hear how it came outI've seen that almost all cranial vaults come up back in F2 in those chicks that have two copies of the crest gene. And finding polish here without the vault gene is quite a headache because we only keep Polish in India for show.
Same with the Silkies I've seen and had atleast. The texture wasn't a problem, because I observed them in the crosses where feather texture was hard- even in F1, the those crossed with landrace fowl had feathers covering their sides, in the Brahma crosses, they were slightly smaller.
