I am a female. Based on your earlier post it seemed like you thought the Easter egger could be female, but it seems everyone believes the Easter egger and Australorp are male
My first chickens are roughly 10 weeks old now. Our black australorp has a much more developed than the rest of our flock. Slightly concerned she may be a rooster when we were supposed to have all hens due to local regulations on roosters. Any opinions would be helpful.
