I have a doe that for the last two years in the spring the other does eat the hair off of her. It is completely down to the skin on her sides. I removed her from the pen last year and they strarted on another one. It just happens in the spring. I called my vet that does about 15 other farms and he said that there were 2 other farms had the same thing happening but didn't know what the cause was. Also said the deer looked to be healthy just like mine. Has anyone had this happen and know a solution?
