Sometimes you have to offer a new "food" more than once before a goat will try it. Apple slices; one of mine loved them right off the bat, two sniffed, turned and walked away. Next time, one was mighty curious about the food the other was obviously enjoying, tried a slice, liked it. The third couldn't stand the thought of the others having something he didn't, tried a piece and yum. This does not always work though, mine still won't eat animal crackers no matter how many times it's offered. Offer them a few more times before giving up and see if that works. All else fails, crush them up until powdery and drench them.
