I have three turkeys (out of 8) that have dry crusty legions on their heads, eyes and over their beaks. One of them scratches at the sores. I do not know how to cure them, and if a cure is possible? Any advice on what they have? Cure? Are they safe to consume? Any suggestions would be greatly appreciated! Thank you so much This poor guy is the worst, but his other eye is clear, so he is still eating and moving around.
