One of our ewes had twins Saturday morning and rejected one of them. The lamb might have spent an hour out in cold rain before we found her, but we got her dried off and held the ewe multiple times for the lamb to nurse to get colostrum in her and see if we could get them bonded. By the evening, however, her condition had deteriorated, cold mouth and stiff weak legs, and we brought her in the house and started lamb replacer, 2 oz every 2 hours for 48 hours. She had been doing pretty good, good appetite, curious, alert, but has never moved very well, stiff weak legs. Today her appetite has diminished some, taking just 2 oz rather than the 4 oz she was drinking yesterday, and she's having a lot of difficulty moving her back legs. We did have her out of her box a lot more today to try and allow her more movement, so could she possibly just be tired? She's still urinating routinely, has a warm mouth, and has occasional bowel movements. I'm not quite sure what to do to keep her from deteriorating further - maybe I got milk in her lungs and it's pneumonia setting in? Sometimes I think she's breathing a little heavy and then other times she seems fine. She's our first bottle lamb so we're uncertain as to what's normal.
