Hello, I am new to having chickens, and also this website. I have a rook question, I have ten chickens, 4 buff Orpingtons, 4 RIRs, and 2 EE's. I think one of (or both) my Easter eggers may be a rooster. I bought them all as pullets, and have been under the impression that they all are female but recently one of my EE's has started a kind of quiet crowing in the mornings and evenings. I have read that in an all female flock one hen may be dominant and crow. They are about 16 weeks old, I feel like they are old enough to judge but I am still unsure. They do not have Spurs and their combs aren't to much different from the others chickens. Just the crowing is throwing me off. I will try to add more pictures soon. Any advice would be much appreciated! Thank you.
