I am really not sure how much hay I need to feed my horse. She is a small horse, but I haven't had a chance to actually measure her height yet. My guess is that she stands somewhere between 12 and 13 hands. I know I am giving her enough hay, but feel like I'm giving her more than she should have.
Right now I am not working her very much, I will soon be doing more lunging as well as other groundwork. There is no grass in her turnout and I don't usually have the time just to sit and hand graze her enough for it to count.
She is really out of shape right now, and a little overweight, so it's especially important that I don't feed her too much, and I obviously don't want to give her too little.
