I suspect, if they're already half way down, they were there but perhaps got worse suddenly, which is why you missed them previously. Or perhaps he's got pretty funky feet anyway, so ridges & such are 'normal' for him & the cracks are just one small step more. Some good hoof pics would help us give you more than a guess though. Check out link in signature below.
I'm guessing you actually mean horizontal cracks, not that there are lots of vertical cracks? Could be abscesses that blew 3-5 months back on the coronary border, or a laminitic 'event'. Considering they sound reasonably major on all feet(albeit worse on fronts) at the same time period, if it wasn't a systemic laminitis attack, I'd say mechanical trauma(ie 'road founder') was likely if they were abscesses. Are the ridges around the whole circumference of the hooves? Are there other horizontal ridges or lines? Flares, etc?
A friend suggested just moisturizing his feet daily and it will just grow out.
They will grow out. I would suggest ensuring the horse is kept well & frequently trimmed, and ensure there is not undue pressure on the walls while they are, to minimise possibility/severity of any breakages as they grow down closer to the ground. But I'd most definitely avoid any 'moisturisers'. Firstly, hooves don't need it & can't absorb it(yes, despite the advertising!) but also it's likely there may be infection present in the cracks(another reason for frequent farriery) which may have to be dealt with & treated, of which putting topical goop on will only make for a nicer environment for the bugs.
