help me. new horse. bad tummy.

Hi. I just got a new horse on loan four days ago. First day she went great and settled in just nicely, she's gone from living with two other horses to by herself.
She has gone onto richer grass than she has had in the past, but she's only on it three hours a day, and stabled the rest of the time.
Her tummy is making really loud gargling noises, and her poo is really smelly, and pretty loose.

Im not sure is she's just stressed out about the new move, as before this she wasnt in any work. Or the change in diet and excercise has affected her. She looks great and doesnt seem ill, apart from lying down more than expected.

Has she got colic? Or do you think its nothing to worry about....

Let me know asap, im very worried about her, and it doesnt help that its not my horse.

If she was on grain at the previous place, and you're feeding her something different, you need to make that switch gradually over the period of about 5 days, or stomach upset can happen.

Also, if she went from having buddies to completely alone, most horses do not do well in that situation. They are herd creatures and need to be with other horses.

I've never had a horse colic, but I think lots of gut sounds are better than no gut sounds. Hopefully someone else will answer.

Yeh this is true. Im hoping she's just getting used to everything. I just done like the idea that she could be lying down more than usual.
She does have a bad leg that needs to be stable bandaged when she's in.
Maybe that's the reason for her lying down
Hopefully when she gets into a routine, and starts moving about a lot more, she will seem healthier!

Loud gut noises are good. Change over slowly if you can. The laying down part. Is she in a stall or outside. If a horse goes to being alone after a herd they can get sleep deprivation because no one is there to watch over them when they sleep so she might be tired do you have any other animal to sit with her while she sleeps? Even you could sit with her an hour or so in a chair doing nothing so she could shut her eyes.
