Agustus (almost 3 weeks old) has a spot on his side where the hair is all gone. It is in the shape of a donut. He itches at it with his back feet. It looks like dry scatchy skin but NOT red. His mother was wormed after kidding. He does still nurse. He is the weakest of our three kids. All my goats are a little itchy. I can't see any lice and no signs of mange. I tried to clean out his stall but the hay is frozen on the bottom like a block. I did put fresh hay down. Should I worm him? He is overall weak though still standing. I put him back in the stall with Wildflower and the other two kids. I am worried though.
