I usually feed what mama has been eating which is Omolene 300 and horse quality coastal hay. I have however, used the Equine Junior on a few, but had a really big boned colt develop OCD while on the Equine Junior. He was also getting a flake of alfalfa and one of coastal a day too. Apparently the Equine Junior is a "complete feed" which means you don't need to feed any hay....I kinda like feeding them hay though. Gives them something to do all day. Really, any 12%-14% feed will do him just fine with a flake of coastal hay with each feeding. Of course, if you're having as hard a time finding hay up there as we are down here, you might as well go for the alfalfa.........costs just as much right now, and is easier to get. Its pretty high in protein, so he may get a little hot while on it, but if you can give him one flake a day and a flake of coastal a day, he should do just fine. Watch his condition, and be ready to back off feed if necessary.
