Should I stable my cribbing TB, fields are really muddy

[redriverrock]

I have a bit of a dilemma and would really appreciate some opinions. I have 3 ponys...2 native types who cope with anything and a TB who is pretty straight forward until we get to this time of year. We have very heavy clay fields with extremly poor grazing...nothing I can do about it. The fields are very soggy and muddy around all the gates...very difficult to find anywhere that isnt squelching under foot.
The ponys cope fine with this but the TB's feet really suffer and I have been advised by farrier to keep him off the mud/wet as much as possible. This is not a problem as I have a largish yard area with the sand school that he can mooch about in and he seems OK with this...here is the problem, he cribs and at times can be quite excessive. He isnt stressed, no ulcers and has access to hay at all times, has 2 small feeds per day of simple h&p nuts...it seems to just be a addiction whenever he is near post and rail! I could put electric fence in front but it will make it pretty difficult to use the school.
So what should I do...turn him out and let his feet turn to mush or fetch him in to the yard and school and let him crib for england.
We nearly lost him last xmas to compaction colic so really want this winter to go smoothly!

Could you not put him in and cribox his door? Or run a strip of electric along the top of your school perimeter?

How daft am I! hadnt thought about running it along the top, that would certainly work. We tryed cribox or something similar when we first got him, was meant to be extremly nasty tasting, made no difference even when freshly applied!
