I am searching for the best wormer for goats. Any ideas? I have a girl who is getting 2x as much grain/feed as the other 3 does (all 4 are adults), and she is just not gaining weight for some reason. I bought a goat wormer in the pellet form at the store, but she won't touch it.... I was going to use a horse wormer (paste) but I don't want to use it unless I know it's going to be safe.... Any ideas or advice would be wonderful! Thanks guys!
