My Hank is 5 years old, so he's not "old" and as all who have read my posts the last few weeks know that I am having a copper deficiency in my herd. My bucks did not get any drenching as none showed the signs like the fish tails and red colored hair. Boys have no bugs as I dust with sevin and I have never seen any lice at all, Hank has very dry skin and my once gorgeous black shiny buck now has just the dorsal hair as well as the hair on his legs and belly, the hair loss is on his sides.I had seen him rubbing on the fence alot so I attributed the hairloss to that, and he is still shedding out his undercoat from last year as he has these ropes of it hanging from his rump...he is certainly not liking me pulling it off either! I do know that zinc and copper go hand in hand, they just recently got started on Golden Blend minerals and I was wondering if I should wait a few weeks to see if it helps or go ahead and give a zinc supplement? What type of zinc should I use? Are there ANY adverse affects? Is there any way besides brushing to get the dry skin off of him? I have aloe vera juice that I can give to him...how much should he get to make a difference? He weighs 55 pounds.
