I have been reading alot about those collars? How long have they been out? And I can see the issues of breaking a bad habit.

I know you were kidding about the cattle prod RPETRACEK, but the kicking chains have worked for a friend of mine.. when they figure out they can't kick.. after only about a week they usually stop.

And hobbles can be used also like P8ntcrazy said. And most of us have a set of those. IT sounds like she is just cranky and setting dominance if she gets worked enough and gets plenty of eats.

I would say try the chains or hobbles.
