impact on hooves of pea gravel in corrals
I am investigating putting pea gravel in some or all of the corrals where I feed my horses. Most of these horses are barefoot. The idea that I have heard is that if you do this, it benefits horses hooves and limits the amount of trimming required. The reason this is of interest to me is that one of my horses is a half-Arab, half-qhpaint. He was completely wild when I got him at about six and had never been trimmed. He had lived his life on 450 acres of rocky ground. His hooves were perfect and I really couldn't beliee how nice they were. Since he's come to my place, he requires very frequent trimming- but for six years perfect hooves - not even small crack, angles great. I know that doesn't work for all horses.
So, what are the ideas of pea gravel for corral footing. Benefits? Detriments? Considerations?
ETA -mud is not a problem in my corrals.
