I've been thinking about this a bit more since getting a couple of replies in my Inbox.
It wouldn't surprise me in the least to find out I'm so lacking in attention to detail as to miss something as obvious as being able to tell males from females as my mind has been pretty much like scrambled eggs this year. If that is true, then I am definitely going to have to take a lot more notes with this next bunch of eggs I hatch out in a few weeks! I swear I havent been able to tell my males or females that early though and often times cant even tell the Ws from the BWs let alone a SW. Seems like Paul or Mike or Jean or somebody also told me that you cant tell until they start getting their pin feathers in and then they could be a male if they have dark pin feathers on the back and breast.
But, if you saw the pic of my W pullet this year that I posted on the ABC and that all the black ticking, then that cant hold true either. Btw, Ill be posting a pic on ABC of another weird colored pullet pretty soon. It is the oddest looking thing and I'm sure would throw someone off as it has BW male like feathers in the chest and back.
Happy, it's hard for me to see the pics real good but if I had to guess right now, I'd say you have two Wheatens vice Blue Wheatens as the wings seem to be a little dark for a BW. And if I had to guess, I'd say the one of the right "might" turn out to be a male just because he looks bigger and more boy-ish but that is purely a guess.
Having said that, now I'm really confused because Halo says the one on the left could be an EE. This sounds like a case where a bunch of females are running together with a male(s) and then the eggs are collected. I just don't understand the statement, "its likely I sent you an egg from the EE. You'll know more as they grow up, they will look very different from the Ameraucanas." So let me ask, when you ordered the eggs what exactly were you getting/asking for?
I ask because from the title of this post and the original question, it appears as if you knew you were getting a BW. The ONLY way to be certain one will get a BW is to cross a W with a SW. Otherwise with the exception of a WxW or SWxSW cross, you could wind up with W, BW, or SW.
God Bless,
