What are the scabs on the face? They do look like fowl pox, but the chicken also has eye bubbles which can be a sign of mycoplasm or MG, a respiratory disease. Sometimes it can be a secondary infection in fowl pox. I would clean up the face and eyes with saline eye wash or plain saline (1 tsp per quart of water, boiled and cooled.) Then twice a day apply either Terramycin eye ointment or plain Neosporin ointment to the eye twice a day. Tylosin powder which is found online at pigeon supplies, can be put into water for 5 days to treat and bird with MG symptoms. Fowl pox, if that is what has cause the scabs, runs it’s course over several weeks. If those are peck wounds, they will eventually heal.
