Thank you for all your replies! The horses are fed grain in their stalls and then have hay in the pasture, so there is no chance of the sheep eating thier grain or anything. I am aware of the copper issue and am super careful. I only have 3 ewes, they are just pets so there wont be any lambs to get underfoot either lol. I do have a bottle lamb, but he is kept seperate. Thanks again! Heres a pic of my darling bottle lamb, Lyric.
