Supposed to be Buff Orpingtons. . . Have I been conned?

Orpington or Sussex, a pure buff chick should (I believe) be solid colored at hatch. Those dark markings indicate mixed breeding somewhere.

Thanks for all the comments. Well the mystery is solved in that appears to be a genuine mixup involving wrong eggs being sent,Buff Sussex rather than orphs. :-(.....These things happen I guess. ;-/
