Your Fella has bulked up standing at that round bale longer than you realize - lollollol
Why should he go-grazing when the candy dish is right in front of him?
On a serious note, if he is choosing to stand and eat all day long, instead of moving around, that might be a very early warning sign of insulin issues. My IR horse has always been like that - he would rather stand in the barn and eat hay, than go forage for grass on 22 acres - my gosh he'd have to walk up and down these hills all day
Not saying your horse has insulin issues but if he'd rather eat at the round bale without coming up for air, it's something to keep an eye on
1. I use Tough-1 easy breath muzzles. Horses that can easily breath thru them are not quite as inclined to rub them off; not quite being the operative
These aren't as constricting, are really light weight, and do have a breakaway that will work UNDERNEATH the face mask if the horse gets hung up. Saddles Tack Horse Supplies - ChickSaddlery.com Tough-1 Easy Breathe Grazing Muzzle <>
2. Face mask - put a face mask with a double velcro latch over the muzzle so his Buds can't rip everything off his face.
2.1 Adjustment -- the adjustment has to be pretty much perfect to not only allow the horse to eat and drink water but to keep it from being easily pulled off of flung off.
Believe me, I've experienced most of the tricks which is why I spray paint the outside of the grazing basket with Automotive orange paint. Trying to find an spray-painted orange grazing muzzle somewhere on my 22 acres or flung across into the neighbor's pasture, is a whole easier than solid black.
3. Grazing muzzles only stay on during the day. The horse needs a break and night time grass is much safer.
4. For rubs, until he builds up callous - Dr. Scholl's corn pads work nicely for that but you have to take the dirty ones off every night and put clean ones on the next day. You can easily cut them to fit.
4.1 Speaking of cleaning, wash the muzzle with hot, or very warm, soapy water every night to get the yuk off. Soap will help prevent Yuk build-up as opposed to just rinsing it out with the cold water hose. I use Dawn dish soap.
Hope this helps
