Yeah, I thought Cuckoo would be silver but an odd choice. Birchin, possibly because they have the Columbian gene? I don't know if Marans are Recessive or Dominant White, but I know Orps can be gold or silver-based under the white.
It's just odd/puzzling to see such an atypical bird some out...
So would it be plausible to assume that Cackle's breeders aren't pure for Black-tailed Red? And that it's possible they don't cull off-color individuals from the breeding program?
It's true that conventional sex links may not have feathered legs, but I can create Black Sexlinks with a Black Copper Marans rooster over Cream Crested Legbar hens to get feather-legged birds that, at a glance, look like a Black Copper Marans hen. Usually, there's some small head tuft, and of...
That is a better picture of him. If the hatchery says it pops up, then it's got to be a throwback to whatever has been crossed into them to get/maintain the variety. Did you get any pullets of the same variety?
That's my point. He's not a pure Marans, especially since he was in a mystery box. He honestly looks like a Red Sex-link rooster with a lot of leakage.
@Amer - you're good with genetics.
Cackle should be ashamed if that's what they are selling. That bird is a mix.
This is what they claim their birds look like:
The leg feathering is much better on this bird and the color is correct-ish. Your rooster has nearly no feathering on the legs. It also isn't built like a Marans...
