Depends on the bloodline really. Some can end up very red, some very orange. Both are "normal" (if there is such a thing with Corns!). There's a wide variation within the morph. The best way to get some idea of the potential adult colouration, is to see the parents.
The yellow pigments develop more slowly than black or red, so any that will be orange are likely to show this slightly later.
As a similar thing, I've hatched odd Amels that have been so pale that hey might have passed for Snows. After 2 or 3 sheds, they looked like standard Amels. The colour changes in the early months can be pretty drastic.
