Here's another thought...she's the only horse in the barn with a slow feeder net in her stall. It's there because if not, she scarfs her hay SO fast and then she's left with nothing to munch on after about 6pm which I know can't be good for her
BUT could the slow feeder be causing some of the issue with the foxtail? I read that most horses will eat around it, but if she has to pull her hay out of this slow feeder, could that be partly why she's grappling with it?
And if so, what's worse, leaving it there and having these ulcers continue to fester, or taking it away and having her stomach empty from 6pm until 8am the next morning?
UUGGGH why can't I live on a horse property?!?!
