I can't answer about the corn, I am sure someone else w experience in that department will come along soon, though.
As to the frogs...do you live in a dry climate? All my horses' frogs have always been hard and dry when in the desert, which is expected and is normal. So long as they are clean, they are fine, no "oiling" is necessary. On occasion they will get a little flap here or there that hardens in place and traps dirt which I just cut off to keep the dirt out. If it is not a dry climate, then I still don't think oil is in order - but if and how his frogs make contact w the ground might need to be examined.
There is just as much horse sense as ever, but the horses have most of it.
