My preg. mare acting funny, thought maybe she was colicking but vet said no, he said when they colic they stay down and are in pain and roll, my mare has been down 3 times since 2:45, she gets down rolls a couple times gets up and eats alittle, her tail is really swishing side ways and up and down, she will eat for a while than in about 45 minutes she goes down agian, I checked her volva and it is pink in 2 places, vet thinks she is just strting into labor. this wouldn't be seizers would it, The vet said he could come out but I told him I would wait awhile. Do you think she is in her first stages of labor?
