Pumpkin Hulsey Color Genetics?

no idea, but cool tail feathers

Pumpkins actually have several color variations, the one in your picture I recognize from GreenFireFarms. I have one that looks like that another that is creme shade of orange, and yet another that looks like a wheaton. Most of the hens seem to be wheaten with a variations on the roosters. I do have a creme hen, and what appears to be a partridge hen all of them from GreenFire.

I do of my oldest roo, the other roos are still young and haven't filled out fully but I'll try to get some shots tomorrow.
His name is Pumpkin... LOL

Have you got photos of the females?

The colour being variable might fit what I was thinking.

I have had my eyes on these for a while. The color is very interesting,  especially the roo from Greenfire. I know very little about gamebirds, but it would be worth the time and research. Not to mention building a new pen...Or at least convincing my hubby to do it.
Do they all come in those three shades (redish, mahogany, cream)? Is there a red gene that acts like Andalusian blue? I think that one might need it's own post.

so far as I know no one has done an in-depth study on what causes the pumpkin color and its variants. a white pumpkin has the silver gene rather than the gold, and there is a variant of red pumpkin similar to the very pale bodied roo posted that is called canary. it seems to be partially dominant but I'm not sure as I've not bred them nor tried any crosses. I've seen birds from a single mating that half of them came out pumpkin from a family that never throws pumpkins bred to a pumpkin family and then the other half of the brood all came out normal color. the majority are wheaton based, but most red American gamefowl families are.

the color also seems to at times only show up after the second or third molt, or in only part of the body. For example, a perfectly normal looking wheaton male with pumpkin/canary shoulders.
