:help!: Why do horses poop and urinate on their hay if it is on the ground? My little 5 month old colt keeps urinating and deficating on his hay! This is the first time I have ever seen something like this. I mean, it's not like he dosent have anywhere else to do it,lol. If anyone knows why, PLEASE tell me, so I might be able to take care of this issue before it gets out of hand.
