I have a Polish roo that a couple of days ago I noticed that the back of his neck and over his right eye is missing feathers and is sort of scabby and dry. I have been rubbing vasoline over the area a couple times a day but the poor guy is still itching up a storm. I know he doesn't have mites or any other type of bug so I'm pretty stumped. What else can I do to help him get better? Should I put some sort of anti itch cream like Cortazone or something else. Help Please!!!
