These two are the one in question. They were in the bin labeled Ameraucanas. The bright red combs are what are making me think Roo but from researching I have found a lot of pictures that make it look like that is normal for this breed. I see no waddles forming.
Top one is Mary Poopins AKA Big Bird
Bottom one is Shelia ( my son named it )
That is quite a lot of comb for 6 weeks. In the group photos it *looks like* they've got green legs which I believe makes them Easter Eggers, but that's one of those things retailers do. My understanding is that a lot of the white and black patterns do tend to be male- also EE's don't usually get wattles- just combs. I'll toss my guess in as both are cockerels- haven't had any EE cockerels myself but I have a couple pullets that didn't pink up until quite a bit later.
Great job with the photos!
