Advice on treating the face of a "Biter"

[Pandemic pandemonia]

Hi! I hope everyone is having a wonderful 2021 so far. I'm hoping someone has some advice that will help me.

I've got a chicken that needs treatment to wounds on the face, comb, and wattles. My problem is that this bird is a biter and to be exact, a hard intentional biter. Said bird hasn't always been a biter, in fact, this just started this morning, as I was trying to clean up the wounds more and apply more antibiotic ointment. I tried cleaning the head last night but it seemed painful so I did as much as I could. One wattle is slightly ripped away from the beak so I can't hold them. I feel like every part of the head is painful, so that's probably why they're biting, but the wattle especially needs attention. Thank you for any and all advice, tips, tricks, suggestions.

I wonder if liquid bandage might work. I do think it stings. I usually leave wounds on my roosters combs alone and they do ok but on the waddle I can see your concern about infection. Good Luck
