Oh and I forgot to add that, in order to show willing, I have bought Echo some 'hormonal mare' supplement. She has now broken the fence in 3 of the fields and they are having problems keeping her in any of the paddocks, as she just jumps out or breaks the fence. She has even been known to give the battery for the electric fence a good boot and break it, then duck under the not-so-electric-anymore tape. I am rather embarrassed by this behaviour, and although the yard owner is lovely and says that it's just 'horses', I felt I ought to try something. We'll see how it goes. It might also help towards solving her stiffness - you never know!
