This morning, our Penny wan walking and moving around normal. Even when we first went out this afternoon to give them more hay, she seemed fine. Now suddenly she is having trouble getting up and walking. Her own momma shoves her away from the hay when we bring it out... I'm worried about her, but not sure what could be wrong. She's had a good appetite, seems to get enough to eat, although she is smaller than the other kids, even her twin sister. She doesn't act sick in any other way. I haven't been able to check her temp as of yet, but no labored breathing or discharge, or anything :-( Please help! Any ideas would be appreciated!
