I cold hosed the leg for about half an hour, and got my mom to call the farrier since my instructor was busy (and I felt like my farrier might be of more help). Once she limped back to the cross ties, he arrived and sweated and wrapped it for me.
He put some DMSO on it, and she stood still like a champ. If anything, I'm really happy with how she coped with it. She got a nice apple afterwards. Once her leg was all wrapped up, we hobbled to her stall. I cleaned it out and loaded it with straw.
My instructor is giving her some bute for supper and she's going to cold hose the leg and re-wrap it for us in the morning. She'll likely turn Indie out in the smaller pasture with the donkey, although I doubt Indie will move around at all.
So, vibes please that Indie starts feeling better? I'm just hoping it was an accident and nothing too serious.
