Does chicken with bumble foot have a comb problem

[Beloved Turkey]

My chicken who I’m treating for bumble foot is healing well, but I’ve noticed that her comb is getting rough and seems bluish at the top before getting white. Is this normal, and if not how bad is it and how can I help her

Looks like dry skin to me.
I wouldn't worry too much.
