Good morning! The white spots on the comb look sort of like a fungus. If it's indeed fowl pox, it's very early in the process. The feet, I don't know if it's anything I'd be very worried about.
For the white spots, regardless of it being pox or fungus, some Blue-kote would treat both. Pox can only be semi-controlled until it runs its course. The Blue-kote may help. If you have no Blue-kote, paint on some Betadine each day. Both will dry out the lesions and help them heal more quickly.
The feet I would try soaking in Epsom salts and scrubbing them with a fingernail brush for a few days running and see if that helps.
