I may be over reacting, but today we went to the barn and Selah (8 month old foal) was, laying down. We didn't think anything of it, just thought she was sleepy. Well, not very long after, she started making these weird noises. Honestly, it sounded like a chainsaw. She was laying down, her eyes were open but rolled back kinda, her mouth was wide open, and she had some diarea. All that laying flat on her side. We tried saying her name, snapping our fingers, nothing would get her to "snap out of it" Finally I jumped in the stall with her, and after a while she stood up and didn't make those sounds or anything again. I thought it was just a stomache ache...what do you think? I'm really worried about her, I mean I don't want to walk in the barn tomorrrow and find her dead :(
