WBS Ameraucanas are one of the three breeds that I raise and show. You are going to have to wait until they are at least 4-6 weeks old to be sure whether you have males or females. Even distinguishing between Wheaten and Blue Wheaten can be tricky at times. I had a couple of Splash pullets this year that I wasn't able to tell they were for sure Splash until they were like 8 weeks old.
I have one Wheaten pullet right now that I would've sworn was going to be a cockerel. She's got way too much black in her. I think there may be some pictures on my website that you may find helpful.
I had planned to do a week by week photo journel of my Ameraucanas this year but I wound up having just way too many irons in the fire to add one more thing to do.
If you can post some pics, it may help.
God Bless,
