I am in idaho, and I had only ever delt with a colic once with a friend. I noticed that something was up with my mare and we went to the vets. He flushed her, she came home, was acting better that night, and for part of the next day. She only ever tried to lay down and roll once and I got her up quick, but other than that, my only indication that something was wrong was that she would lay down and just lay. Or be standing and kicking her belly (not often), and that she wouldn't eat or drink. She spent the night at the vets Wednesday nigh, and Thursday morning they said that it would be sugary or to let her go. I let her go...she was a starvation case and the vet said that it is likely that being starved had something do with it.
