The next day was even worse. Fortune got very colicky. I've seen it in other horses, but this time I felt almost responsible, and quite helpless. However, we had the vet out, and now -three days later - Fortune is doing a lot better. His appetite is back 100% and he's drinking a lot better than he was.
Since Monday, I've been out to see home everyday, something I'd never have been capable of with him an hour away. I'm working tomorrow and so wont bother him much, but on Sunday I am planning on riding him for the first time since last Sunday, the day before we moved him.
This is new for me, but for Fortune "new" doesnt even cut it. He's handling everything much better than I couldve hoped for though, and today he seems almost completely back to his old self.
I just thought I'd post this for the sake of sharing. And to thank everyone - again - who offered me advice recently!
