I believe Vega might be harder to find a ration balancer for because she's hypp NH.
Gem's only problem is having arthritis, but I don't think that should matter with what balancer he gets.
How long, on average, would a ration balancer last for? (Is this something we'll have to get every month? Every other month?)
Also, if there's another type of feed that would be good for a horse out of work, I'd be open to looking into it.
