Just put eggs in the incubator for my Silkie crosses.

Silkie roo over EEs, Orpingtons, and last years Silkie-EE crosses (so we'll see some silkied-feather chicks this year!).
Anyone have tips on how to tell silkie chicks apart from silkied-feather cross chicks? My cross pullets from last years hatch have all the silkie traits aside from feathers (crest, fibro, extra toe, feathered legs, etc) soooo.....
I do know, at least, that all my pure silkies will be black, blue, blue partridge, or poooossibly white (I have one white hen but I don't think she is laying). So I know chicks of any other color are crosses. But it's the cross chicks of those colors that I think I may have trouble identifying. And before you say it, yes, the silkies and the silkie crosses lay the exact same egg!
