Pat, I don't sell any kids until they've been weaned, and most goat breeders are the same. As far as castration, that's usually the buyer's task. Shots for kids are CDT and rabies. They should also have BOSE shots, which isn't a vacination, but is boron and selenium. The hardiest breed is probably the Boer goats, and they're probably less pciky about what they eat. I think that Pygmy goats, although small are very hardy, and less selective about their browsing.
