Anyone know what this is? Silkie Roo with White Spots on Comb

[trishmk]

Have noticed this over the last month or so on this Roo only. I've never seen any mites/bugs and use DE regularly in Sand Floor Run/ Wood chip coop. Does not come off with water. Think it's something I should be concerned about?

Thanks!

If he is healthy otherwise... I wouldn't worry. Is it possible that some of the earlobe pigment is some how seeping to the comb? Silkies can often have whiteish/blueish/greenish ear lobes, and perhaps some of those pigment cells are on the comb? Not really sure.
