She looks as though she's trying to find some nibbles now. Cassie, do make sure she has enough hay throughout the night - or keep giving her a new small bundle when you go to check her during the night. Some mares like to eat as they approach foaling - in one end, push it out the other LOL!! - and she wont eat too much, she hasnt enough stomach space in there right now! i know others might not agree with this, but I can only say what works for us, and I find it much better for the mares to have several small feeds of hay during the night as it keeps their energy up, plus stops them diving into their morning feeds/hay and eating too quickly because they have become hungry.
I have also found that this is another good way to get possible imminant signs. Give your mares regular small bundles of hay whenever you pop to the barn to visit, watch for five minutes or so and if everyone is peacefully munching, then a foal in the next half to an hour is unlikely - time therefore for yet another cuppa or a bite to eat for yourself! LOL!!
