That is a very pretty mosaic :) Now there's one that can't be anything else. While ash-red cocks can have so much blue it looks mosaic, a bird can't just express dilute on one side without something funky going on.

I also like the half-sided pied, which I believe is not the same as mosaic. I have seen too many pied birds that just happen to have one white wing while the other has color. But that's just my opinion. A lot of breeds over there are bred to turn white when they are plucked a few times so they could easily (easy for them, not so easy on the bird :eek: ) turn them into whatever kind of crazy white pattern they want.

I agree completely! The dilute ash red one is amazing, I guess there is a very minimal chance of some kind of weird mosaic half sider with pied on one side of the shield but highly unlikely.

Wouldn't that have to be recessive with the colored flights and tail and not ash? Anyways i wonder how halfsiders breed out. For the sake of discussion, if the bird was a male bred to a RY i wonder if you would get both yellows and reds, just reds or just yellows. Would one side be completely dominant over the other or what? If that was so i would assume it was the RR side because it has the tail, head, and a spot on the yellow side.

Mitotic crossing-over or nondisjunction would be a valid explanation for this yellow/red halfsider too. Genetically this would need to be a male het dilute D+/d.

Yeah your right, Oversight on my part. No Doubt it is reccesive red with dilution on one side.
