Last night I caught Lena laying down on the camra. Not ten minutes after I started watching she got up. Though tonight, she was all weird. She kept going from grain to alfalfa which were at seperate ends of her stall. Kept lifting up her tail, and acting like she was distracted. So I left her, and took a shower. As soon as I got out of the shower I checked the camra, and what what she doing? Laying down. Maybe 15-30 minutes later, she was standing. Now I just checked again and she was laying down.
