I woke up this morning to a doe laying down in their house. I went to check on her and she hopped up and seems to be favoring one of her back legs. She can put pressure on it but she lifts it back up. She is able to scratch herself with her foot and that doesn't seem to hurt her any. I'm not sure what's wrong with her and of course she is one of my goats that won't let me touch her. She is very skittish and we have been working on that. Is there something that I can give her for pain? What could be wrong with her? I'm new to goats so this is all foreign to me. Thanks!
