Recently everything has started growing and we have a lot of new green grass. I noticed my mustang had some diarrhea so I put her in her stall for a while and she seemed to do fine. Everything went back to normal. Well I was going to keep her in at night, but I didn't last night and didn't get her in until tonight and she had diarrhea again!! So is this normal? Cause I don't want her to have anything serious, I am thinking it is cause her stomach isn't used to taking in all this green grass after winter? I was also feeding her 1-2 flakes of really good bermuda hay a couple days ago and I stopped that. I am hoping everything will be fine by tomorrow, but I wanted to make sure I wasn't missing something serious!
