I usually have the Farrier come out every 8 weeks. He trims them very nicely and then uses the rasp to file them. But within like 2-3 weeks after him trimming, they CHIP LIKE CRAZY! I cannot figure out what the issue is. I was thinking maybe he was trimming them wrong, but he does a wonderful job. My horses are on flat non rocky pasture. I don't ride them super hard. They have gone barefoot for all the years I have had them, and it seems like this year their feet are always horrible. I have 3 horses and 1 donkey and at $25 per horse I cant be getting them trimmed every month! Any Ideas? Are their feet too dry? Should I start using hooflex? Thank You!!
