Hi, I'm wondering if anyone can help shed some light for me. We have three chickens; Bonnie, Bow & Bella. We were led to believe that they are 16 weeks old and all females by the person who sold them to us 10 weeks ago. We believe Bonnie to be a Light Sussex but were told that the other two were black Orpingtons - this we do not believe! They have grown so much in the time we've had them and are beginning to show their own hilarious personalities! We've not heard any crowing but we're not sure if they are all females. Please help! THANKS!
