My 5 and 6 year old boys wanted chickens and I was more than happy to help them build a coop and get some birds. I've had these for 10 weeks, I believe they were between 10 and 12 weeks old when I brought them home. No crowing yet! The boys have named these birds so I need to get out in front of any rooster issues. We live in a neighborhood and a noisy rooster could potentially be a problem. The first picture I'm reasonably confident is a hen. The second I'm quite sure is a rooster whith a hen behind him, and the third pic I believe to also be a rooster.
