For the past year Misty's hooves have really changed... she's never been shod and her feet have always been good, but now they're constantly cracking and chipping, and they grow at the speed of light; the farrier is here every four weeks, sometimes sooner! Before she only needed them done every eight weeks, sometimes ten.
I'm thinking of buying some sort of hoof conditioner, but could it be due to age? She'll be 24 in September. I'm buying a new mineral block tomorrow, she hasn't had one for a while.
Anything else I can do to improve them?
