Currently, she is being fed Purina Strategy and hay. She also gets Dynamite added to her feed each day.
I plan on keeping her on the Strategy, but I'm not sure about the vitamin? I've never been a huge proponent of giving extra supplements if they aren't neccessary, but she will be my first young'un, and also my first horse in Colorado. Maybe she needs it because she's a growing girl? I don't know. Does she really need one?
If I do put her on a vitamin supplement, I was thinking of trying Farnams Vita Plus. It's a lot easier to get than the Dynamite and I've heard good things about it.
