A picture is worth 1000 words, so I noticed her like that this morning, and when I checked on her after lunch, she was still like that (different place though). I put some food in front of her and she pecked at it a little, but not like the other ones. This morning I did notice a small amount (size of a nickle maybe) of diarrhea on a piece of wood, but I have no way of knowing if it even came from this chicken, and I didn't notice anymore since then. Any ideas? Is this something to worry about?
