A friend just purchased 2 horses and is keeping them at my place while he finishes his corrals. 1 is a 2 yr old stallion and the second is his mama. They have been at my place for 2 days now and this morning everything seemed normal when I fed them. At lunch when I came home the mare was laying down and I thought nothing of it but when I came home this evening she was still laying down but in a different spot. At feeding time she was still down (only on her knees not fully layed out) and I havent noticed her biting at her belly or kicking at it. I entered her corral (20x20) and tried to get her up but she refused. When I got the food out she did get up and began to eat but eventually layed back down (on her knees) and continued to eat. I have never seen this behavior before and wold like some advise. I already called the owner and gave him a heads up that he may need to call the vet but I don't know what else to do. She was brought from a large pasture where she was with 5 other horses and she did leave a 3 yr old daughter behind. She is now in a 20x20 corral with the stallion son with my 2 mares on the other side of the fence. PLEASE ADVISE.
