I'm trying to figure out breeds on a couple of my pullets. I bought Shadow, Coco, and Cinamon from a lady that said they were Olive Eggers. I've heard that is a general term for an Aracuna mixed with anything that lays a brown egg.

This is Shadow, and she is about 18 Weeks old.

Shadow with Coco in back.
Cinnamon and Coco look exactly alike, and all three came from the same hatch.
Then I have Gina, and Lulu, who are 3 weeks younger. We bought them from the feed store, and they were both said to be Silver Laced Wyandottes. Lulu obviously isn't. I was thinking Australorp, or maybe Black Jersey?
