Hey everyone! I need your expert advice, as this is my first time with chickens... I've ordered Black Australorp and Barred Rock chicks, but I'm splitting an order with a friend and need to know which are hers and which are mine. Neither of us want to end up with all of one breed! I've tried to look at pics on the forum and other breed sites, but BOTH chicks look grey-ish black, with some white on the underbelly and face. Help! How do I tell them apart???
