Hi all! I'm hoping I might be able to get some advice on whether the discoloration (white powdery looking) on this 1 1/2 year old bantam Rhode Island Red's ears and the blackish ends of the comb seem normal. She's happy and laying well, but the new pullets have also developed some whitish discoloration on ear lobes and top of beak, which makes me wonder whether it's a fungus or mites (or maybe, thinking wishfully, dry skin?!). I'd love to have the thoughts of someone with more experience than I have! Should I be worried? Anything I should be doing? Thank you!
