Is this dry skin or a yeast issue?

[Ccort]

She's molting a bit around the head but the white/possible dry spots on her comb and the side of her head....is that just from the molt, skin dryness or a possible yeast issue?

Could be Fungal Infection or perhaps some scaly face mites.

Looks like she's molting too.

It won't hurt to apply some anti-fungal cream/ointment to the skin to see if that helps clear it up.
