your pony is fat compared to the one i got from a trailride place at a county park
i feed free choice hay, senior feed or a high protein feed, a little corn or beet pulp. make sure she gets grained on her own so you know she is eating it. the problem with mine was it getting pushed out. it was about 500 lbs underweight. i have never seen a pelvic bone sticking out the top of a horse before. (they were still using it for trail rides everyday!!!!) mine is looking much better now.
good luck sounds like you are going to have a wonderful pony
