So I brought home 2 18 month old ewes Sunday night. It was a several hour drive for them. For the last t couple days I've been feeding them hay and some textured sheep feed. They seem to kind of eat the hay but won't touch the grain. I know it's been traumatizing for them so I didn't expect them to be pigging out the first day. Should I be worried or are they just getting settled in. Any tips for getting them to eat?
