Orpington cockerels?

[MayhemFlock]

I was told these cockerels were pure Orpingtons (lavender and black respectively) when I got them at 4 weeks old (they're 8 weeks old now). A friend picked up a group of chicks from someone off FB so I didn't personally see what birds they actually had on the property. Either way I'm growing them with the intent to keep one for my flock of dual purpose hens (Orps, Wyandottes, and Dominiques) to start producing some meat birds next year. I'm just curious if they're actually Orpingtons or what people think they may be mixed with.

Thank you, I was also questioning the "lavenders" as the color didn't seem right.
