I've been debating about what to do with the outside portion of my horses' stalls since they both like to lay down out there and need bedding, but I wanted to find something that was going to be cost effective... Debated between Dry Stall, Cedar Rest, wood pellets, and shavings...then found rice hulls. Decided to try it ($8/bag) and put a couple bags in each horse's stall. They both started munching it, but stopped after a few minutes, and pawed it. One of them rolled in it. Then it started raining...like cats and dogs! For about 3 hours. I went back out to check on the rice hulls and they are virtually dry!!! The rice hulls are the only part of the uncovered area that is not muddy or full of puddles. Needless to say, I am impressed, and wondered if anyone else has ever used this bedding?
