I have had a few rounds with them myself, but they can be handly in a bad mess that no one wants to get into. I wish I could help. I live just 11 miles from the Ks state line. I run a rescue here, as well as work with the shelter. I have had 8 or 9 horses here that you would have cried over, People can be so mean and just plan SICK sometimes.
The last horse that came to us never left, Reb, what a great horse he was... He is gone now , I miss him. My wonderful hubby got me a rotiron cross and put it up in the pasture where he was laid to rest.
But at least the last 3 years of his life he knew love and careing that's how I have to look at it or I would go crazy ( er) lol
