Is there a genetic test for chicken colors?

[Naamahbengals]

Hi all. I'd love to know what colors my chickens carry for. For example, my old white silkie carried blue, found that out through breeding! But other colors that I don't know about - I'd be very interested in knowing. Is there a test somewhere?

I doubt it. I think the only test you can get done is for gender determination.
