I have two week old olive egger from meyer, one that looks like yours, but without feathered legs, and one is darker, almost a charcoal color. I believe they are legbar crosses since they both have single combs. I would have loved ameraucana crosses since I love their fluffy faces, but maybe I will get one with a crest.
I'm thinking legbar cross, maybe with a darker maran (black of blue). I love the little mohawk crest on my blue one, she didn't get it until about week 3 and it wasn't very pronounced until now. I've found the roo and pullet are both very friendly and inquisitive in personality too. Add to that Olive eggs, and I'll really enough this mix.
