I am new here. I have 3 goats, Nubian mom and her two babies, who are now 2 years old and not babies. This winter it got down to -30 and everybody was miserable. And the goats stopped eating much of anything for a few days. They lost a a lot of wieght, especially since they were kinda fat to being with. So started giving them more grain, which they don't eat. And some nicer alfalfa grass hay which they didn't touch. They drink, but not a lot. I wormed last with Ivermectin 2-3 weeks ago. I thought spring and the warm weather would make them their usual wild selves again, but it hasn't. They lay around most the day, they eat, but not their usual. Typically they are finding escape routes to get to the new buds on the trees and playing 24/7 and eating like pigs. Instead they are sleeping. Zecilly (mom 7 y.o.) has put back on most her weight, her coat is beautiful, she is eating the best and acting her usual self, which is not as wild as the boys, but active. But both boys are still very thin, haven't put on a pound, and are lazing around all day. Usually by now Two is pulling cart and One is escaping daily to destroy a tree, and they are hardly even leaving the barn. My vet isn't much concerned and said she'd give me some stuff for their stomachs. Any ideas? What is wrong with them? What should I do?
