Richie does not seem to know anything is wrong. His balance is fine and he is not appearing to have a fever (his ears are not hot). He's eating well and acting like a boy getting ready for rut.
I've contacted both my vet and an experienced goat owner whose daughter is also a vet for advice. My goals are to make sure Richie stays healthy, and if at all possible, keep that horn from breaking. (Goat friends are recommending a course of antibiotics to prevent infection.)
