Thanks for all the responses!
Yep. The Superfork does look very similar to mine.
Joe, I'll trade you chickens. We have tons of them running alllllll over the place, but they don't clean quite as much as that.
I'd love to leave the horses free range 24/7, but we have predators of the 2 legged kind. I'm completely surrounded by city folk and teenagers so my guys are locked in at night with the barn dogs so I know they can't be turned loose to run down the highway. People can be quite special some times.
Dreamcatcher, I had no idea they made motorized forks and now I'm drooling with jealousy. Drooling. :) I do work an office job, so I consider stall cleaning a form of exercise, so no motor for me yet. Someday though...
I'm pretty familiar with allergies, having dealt with them in the past with a different mare so I'm pretty sure it's not that. The two geldings have been here for a long time and there were no issues until switching bedding. I'm wondering if the TSC brand of pellets is lousy. They turn to dust super fast.
My plan is to switch back to shavings and see how it goes. If there's not a change I'll call the vet for a consult. Thankfully, it's nothing too serious, just the sniffles, but I want to be proactive as much as I can.
