I think that the first step would be increasing hay. A horse should eat hay primarily. Perhaps free choice would be a good option?
As for switching her to an oat mix... you could start her on a supplement to bridge the nutritional gap. There are tons of great supplements available.
What? That's way old time.. Floating your horses teeth when they don't need it will just cause the teeth to be worn down way to much. Not to mention the huge vet bill. Now yearlings should have their teeth floated every 6 months - usually- but doing it for adult horses every year no matter what is completely unnecessary. Some horses may not grind their food properly and develop hooks and therefore need it every year, BUT that's because they NEED them done.. Casey went four years without a float, and I had two different vets that did her shots and said she didn't need her teeth done, but that is probably because she can constantly eat hay/pasture.
Other than that, I agree. Definatley free choice (24/7 access) to pasture or hay.
