Silver Ameraucana feathers turning buff

[Pahlavinka]

I'll post pictures a little later once I can get an up to date pic. But basically here's the deal. I have a silver Ameraucana rooster. He looks exactly the way he should look but hos white feathering is almost turning yellow now. He's a few months under 2 years old. I think this is really strange. It's been getting more and more pronounced in the last month. Is it dirt? Who knows. It looks too specific. Like it's around his hackles and wing bars. Is this part of the genetics of a silver colored bird? Let me know in the comments.

It could be from being out in the sun. I believe the term is bronzing or brassy. It happens to white birds.

I second this. Sun and white birds don't mix well.
