I also think it's likely a late blooming amel, that will "color up" in a few sheds. However, there is one other possibility that I might suggest. If Dad is a hypo, and the clutch contained snows (can't recall how many, sorry), then is it possible that Mom is het for hypo, and they produced a couple of coral snows?
Statistically, I realize the unlikelihood of having two triple homozygous animals in such a small clutch. Even so, it might explain what you are seeing, and once all of the possibilities and impossibilities have been eliminated, the unlikely is all that is left. 
I'd still think amel, until proven otherwise, though. Keep us posted on the progress after a few sheds!
