We bought 4 pullets from a Feed Store (reputable in our town). They are 4 wks. old now. I was told they are: 2- Amercaunas 1- Black Giant 1- Barred Rock Now...I'm wondering about the Ameraucanas...because I see a lot of confusion/mixed notes on BYC about Ameraucanas and EE. How do I tell which of the two mine are?
