The T&A hay has been ugly lately, plus it is not cheap! Why do people choose T&A over O&A? Can I switch to O&A easily? I am feeding a 2 year old paso filly 2 flakes a day, and 2 minis, they each get 1 flake a day, maybe a little less. None of the horses work hard (actually, they hardly work, lol) and they also get grain.
