Switching from hay to grass.
I just moved my horse to the farm that I'm going to be living on. He was on pasture in the spring but had to be move to a paddock with free-choice hay. We moved a mini in as well. He had been in a stall, eating lots of hay.
I put them in the pasture today and they are getting along just great. My question is, do I need to be worrying about them switching from hay to grass this time of year? I know that you have to be careful in the spring because the switch to rich grass can cause them to founder.
P.S. I'm probably going to have lots more questions because this will be the first time that I'm taking care of horses by myself. I've always boarded.
