AMERICANA--help

[Jennings Gamefowl]

the black one which i was told is a purebreed has not laid an egg yet but the mix one in the last pic has laid two and they are white/light cream though.. the roo comb looks like it folds over

If it lays a cream coloured egg, then it doesn;t carry the blue egg gene.

Yes, the comb folds over, which is a trait some breeds such as leghorns have. Hoever, the shape is what I was asking about. It's not a typlical single comb--I'm wondering if it might have a single copy of pea comb--but as I said, I haven't seen one like it before.
