I have a conning in 3yr old Myotonic Buck that is having skin issues for the 2nd winter in a row. He gets this plaque type condition on his sides and testicles. I have done skin scraping(neg), final cultures(neg) and a biopsy last year (could be allergies or vitamin deficiency). He was fine all summer and started back up in November when we moved the bucks indoors. I have been using multimin on him and also added vitamin A, D, and E to their food. Not sure where to go from here. Not contagious I believe, but his son has 1 patch the other buck has nothing.
