This is a Rust. Notice the wing and face. If you bred it to a black or blue, you should have about half the offspring look like it.
She was a Crested Swedish out of B/B/S breeding. Maybe a color mutation from that? Never heard of "rust". No matter anyway, I no longer have any of those.
Rust is a rare mutation, and it's still being studied by geneticists, they're trying to figure out how it works. It is probably incompletely dominant, with one dose looking like that hen, (I have a Rust swede as well) and two doses looking like a very black mallard color. It basically looks like the black pigment of a mallard was doubled, is what a two dose bird looks like. What the gene does is either relieves some of the black pigment, or replaces it with in areas wildtype color. I'm doing a project with my one rust hen, trying to get better expression. For example, you're hen had better facial relief than my hen does.
