While Hair is working on it for me, here's the story. I saw something yellowish and I though she had some matting on one of her eye lashes. I tried to wash it off but I couldn't so I took hold of it thinking it was an eyelash. I felt it give and pulled off some kind of plant material. It was attatched at the end out but then split in two parts and each one kind of rounded and dark on the end. I took it outside to take a picture but it blew off. Maybe something got on her afterwards but it really felt like I pulled tips out of her. I'm wondering if she could have punctured herself on a sharp piece of hay or something.
I guess it could be that maybe a weed or stick was in the hay - that happens sometimes. I can't see anything in the picture of her though.
