White bumps on comb?

[Hennyhoneys]

Hi all!

My EE, Althea, (15 months old) has had these spots for some time, probably 1-2 months. They do not come off though I haven’t been forceful. Looks like a calcium deposit IMO. She otherwise shows no concerns and I do not see anything similar in her 6 flock mates. No lice/mites/etc. Is it dry fowl pox?

Here's a thread that's about the same thing your hen has, by the looks of it.->

I'd try doing what is in the second post, if the bumps come off.
