I was thinking that the only reason she is being fed grain is because every other horse at the barn gets fed it. I don't think she really needs it? I am moving soon and she is going to come with me and I was thinking that maybe it would be a good time to try out all day turn out with hay and just leave out the grain. She's not getting any supplements so yea. I guess my question is how should I go about cutting out grain? And I heard something about the water weight in grass can affect them in weird ways? I don't know, I'm curious.
