Today was the first day the lambs went outside here. The smaller lamb was not doing well; having trouble walking, wasn't gaining weight or eating as well as his brother, and generally not looking so good. Trying to find a vet for sheep has proven difficult, so I gave him a five day course of antibiotics and the tincture of time and he seems to have, hopefully, turned the corner. He has a long way to go to catch up to his brother though!
The other sheep didn't seem to mind the little guys, even though the lambs tried nursing on everyone. But I think the other sheep were relieved when the mother sheep and her lambs went back in the barn.
