I have two 3 year-old Nigerian dwarf goats wethers. Both have been healthy and strong throughout their life. I got them as bottle babies and they have flourished. The weather just recently turned cold. One of them seems to be shivering. He is smaller and less rotund than the other one. Is there a certain food that I could feed him that might help fatten him up in the event that maybe he just doesn’t have enough fat to keep him warm. The temperatures went from 60 down to The 20s and 30s here recently. They have a nice stall that is not airtight but shelters from wind & elements in a barn and they have access to the outside every day. I close them up at night during these colder temperatures and they have bales of straw and hay to snuggle up against. I give my chickens a warm mash to eat on these cold mornings. I’m wondering if Goats likewise could be eating something warm and nutritional. Of course they have access to hay and fresh plugged in water Which I know is vital to a roommate‘s digestion.
