Need more information. How many right hind foot problems out of how many cattle?
Is there a high hill in the middle of the pasture, that they tend to walk around in a circle? If they always made a clockwise circle, the right hind foot would stand most of the stress.
Are they genetically predisposed to being "right hind footed"?
Have you recently worked them, and perhaps there is an imperfection on the right rear corner of your squeeze chute causing that foot to be injured?
Are there leprechauns or gremlins that inhabit your pasture?
Is there a one-horned billy goat that for pleasure likes to hook the right hind feet of cattle?
Could there be a one-eyed snarling dog in the area that molests and attacks the right hind feet of livestock?
Are your cattle Liberal or Conservative? If they are conservative, the right side of them is doing all the work, which could cause the problem.
The possibilities are endless, which is why we need more information to solve your problem. :wink:
