Rooster molting tail and wing feathers? Yellow tips?

[PoppySeedy]

I've never experienced a proper molt before so I was a bit surprised to be finding his tail (and I think wing) feathers all around the run. Im just wondering, is it normal for the tips to be yellow? (Picture attached) i know chickens are complicated so im just wondering if yellow tips are a sign of anything or if I'm just overreacting lol

I think it's just staining from the oils in the skin.
