I noticed what looks like a blackish/brownish spot on my turkeys snood and now it's on his waddles and I have 2 hens with the sopts on their waddles & combs. The spots are dry. Their behavior is normal. I read that I was suppose to treat with Terrimycin so I added it in the waters tonight. Now I am reading not to use antibotics. So I am confused??? What should do??? Just use betadine to dry out the spots quicker and/or give them antibotics? They don't anything ozzing bloodly or wet. Just dry spots. Also how did they all sudden get them? I keep everything clean - the pens, fresh water with vitamin & electrolites (cause it's so hot) fresh good quaility feed and fresh watermelons & grapes often. I take such good care of my birds and really care about each and everyone of them. I know this is not personal ....it just pisses me off! Don't want my birds in pain. Please advise. Thank you!
