How old to tell the difference between Blue and Splash Orpingtons?

I got some black, and some that are blue or slash. The Seller told me that the lighter chicks could be either.

Thanks,

My Splash chicks hatch almost white and the blue hatch from light grey to dark grey.

You can tell when they hatch if they are splash. Splash chicks are a white color with some blueish grey hues. Here is a picture of a splash ameraucana chick.

After a little reading here I made my own realization. The Rooster in the Pen was a black Orp. So I now know all the chicks are blues/blacks.
