We bought these chickens from a lady who bought them from an auction. She didn't know what breed they were. We have done some research and think they are 1 Blue Maran and 5 Black Copper Marans. However, we are not entirely sure. Also, we have no idea how to sex these chickens. Any opinion on sex and breeds would be very helpful. We are new to this "raisin chickens thang" and thank you in advance for your help.
