Thanks everyone. And yes I am working off the AAEP's Care Guidelines for Equine Rescue.
I own the local feed store. And it will cost me $17 a bail to get grass hay brought in.
I now have a call in with a new vet. My 3 other horses are starting to drop their head to the ground and throwing it around. They are not under weight not are they losing. They are acting like its something in the ears and I will have the vet check that when they come out.
