Hello, what is the best ration balancer you have found? I have Icelandics (gelding, pregnant mare, and breeding stallion), and we do a pretty decent amount of work. I am going to transition to barefoot soon also. I heard good reviews from Mad Barn, California Trace Plus, and the Nimble supplement. Anyone have experience with these products and is there anything better? (Ration balancer + grass hay is what I feed).
