I have a 18 month old colt that is eating acorns that are falling off of the oak trees. I have heard of horses doing that. do you know of any problems that this could cause and what I need to watch for if any. I do feed stuff for sand to help keep them cleaned out because I live on real sandy soil. will this help keep him from getting impacted if this could cause that. I was worried about weather it could cause a horse to founder or what. I've never had a problem with this as of yet, and I'm just trying to avoid any if there can be a problem. Thanks
