What do you think? Could my new mare (here for about 2 months now) still be using a lot of her food for growing? Not necessarily up, but out and for internal changes? She eats everything I give her and still is very slim. Or, maybe she is just a slim horse and will forever be this way.
Please, I have no questions about how to put weight on a horse. If what I'm doing now doesn't show me a change I will try the next option, and then the next and so on. I'm just wondering if maybe no matter what I do, she still just trying to catch up with herself at 5 years old.
