I would get im a cribbing collar they look painful but they arent. Feed him little and alot. Keep him her out of her stall if that's where she cribs bc she probly is bored. Also I recomend Getting Likits its a horse trat and comes in toys for them. They will be liking so they can't crib. Heres the link these thing should work! http://www.likit.co.uk/home
The Miracle Collar is amazing.
My horse Cocoa has cribbed since she was 3 yrs old. She is now 30.
It was difficult to find a solution to the problem... that is, until someone recommended the Miracle Collar to me.
Its very humane, doesnt inhibit eating, drinking, etc...
She wears it all the time. Only time it comes off is for a bath or when I used to ride her. You can even see it on her in my avatar to the left.
No cribbing collar works for my guy. He cribs right thru it. If you keep tightening it, it can become too tight. A boarder thought my horse needed the collar to be tighter. I was not there. I get to the barn and my horse is nearly passing out, and in distress. I took the darn thing off and got rid of it. I hate collars. They are annoying for the horse and can cause rubs, which really hurt. If your horse can wear one and you don't have it too tight, then that is great. However, not all horses can use them.
That is when we decided to hotwire the top of the fenceline. I bought a solar charger so it is not costing the farm anything.
Sounds like quite a severe case of cribbing. You should get a vet out and explain to you what some of the alternatives are. I think there is a surgery that can be done to help reduce the cribbing.
If you get a vet out I know they will be able to give you the options.
Try electric fencing, and if that doesn't work try the muzzle. My mare is a horrible cribber so I got a muzzle for her...but be really careful with the muzzle.. as with some horses cribbing is a stress reliever and with not being able to crib with the muzzle on they can colic, so if you're going to go with the muzzle make sure you pay close attention to the horse!
i have a cribber. We just outsmart him. He is not out in a wooden fence, but electric. We have it wired high enough on the posts he won't get near it. He gets fed in a rubber dish at ground level, no grain tub hooked to the stall. The water bucket is lowered. The stall has 1/2 mesh metal rabbit fence stapled onto the entire front so he cannot grab anything. ( he can and will crib thru the stall bars onto the metal part). Since I have made these changes, he is fine and does not crib.
This was along the lines of what I was going to suggest. Electric wire, and remove all solid surfaces that she can crib on. In addition to this, feed smaller meals more often. If you can get ahold of some low quality roughage, you could pretty much offer it free choice. If needed, you could even keep water in a rubber bucket on the ground. I would make as big of an electric fence turnout as possible, and put her in with a compatible horse if possible.
