My milking doe has a rough coat and is a bit thinner than I'd prefer. Her hair feels rough and coarse. I dewormed her when she kidded in April. Would this be a feed deficiency of some sort or are their coats normally kind of rough? She is my first milk goat, so I don't know if this is normal. She's on a choice alfalfa hay fed free choice plus approx. a pound of grain at each feeding (half Goat Chow, half COB because she loves it). I give her a mineral for goats. And she has salt and soda. Today I picked up a goat Smartlick, I cannot yet figure out how to feed it and not have them jumping in it. It's a big gooey tub of stuff.
