Yellowing in waddle

[Heatherschicks1]

I have noticed a few times when I have been looking at my chickens that they have a yellowish tint on there waddles. It looked almost looks like powder but doesn't rub off. I keep the coop clean they have plenty of room and free range. I wish I had a picture to post with my question. It's not on the entire waddle and I haven't noticed it on the combs. It's usually closer near its feathers and will cover a small noticeable section of the waddle. I have tried to research it but haven't seen anything like it.

It could be canker or fowl pox. Are the yellow spots like scabs?

No there is no change in the skin. It's still soft" and hard to find anything like it online

Following this. My rooster has something similar that I discovered this morning, it wasn't there yesterday. His is a very small spot on the bottom of his waddle. It's a pale yellow almost light tannish in color. Definitely not hard or a scab. He acts perfectly fine too.

If it isn't canker or fowl pox it could possibly be a vitamin A deficiency. I saw in the web that yellow spots can appear on chickens wattles who need more Vitamin a.

If it looks powdery could it be favus?

Heather, is there any change to the spots now vs when you first noticed it?

Mine did so not sure it's the same as what you're dealing with.
Here's the thread I put up about mine, it has 2 pics of what mine changed to.

They seem fine dont seem sick or anything. I just noticed it was on the waddle about the size of a dime not really big but i did notic it a little near the soft tissue near the waddle and ear.. Vit A deficiency i will have to look into. But they act and eat fine :-/
