Greetings all. This is my very first post other than the introduction page. My name is Ben, I live in Minneapolis, MN and my wife and I just got some chicks about 5 weeks ago. They were supposed to be a week old at the time. We'd ordered a Rhode Island Red, but when we got there they said they were out and that they'd give us one of another breed. We've been raising them all together in a brooder and now in a old dog cage we had. They seem to be doing well. My question though is this: Does this sound like a rooster? This 3rd "hen" we got seems much more aggressive than the others. Right now at about 6 weeks her legs are thicker and orange-er than the others, her comb is much redder (the others are still yellow), and general demeanor is much more confident - when I stick my hand in the coop, she'll peck at it lightly where the other two run away. Think this is a rooster? We can't have roosters based on our permit so I'd have to get rid of him if that were the case. How can I tell? Any help would be appreciated.
