Not really, you get a few that are easy to tell early though. The ones that have pea combs are the hardest to tell early.
Yeah, it is not easy to tell as EE are a mixed genetic bag even with peacombs. For this reason, could be all tan/brown eggs, could be all green eggs.. but half and half is a reasonable expectation.
If you happen to get single combed daughters out of him, chances are way high these won't lay green/blue eggs.
