Hello. I have just found out that one of my girls isn't a girl but a boy! So I have a rooster, and I'm a bit nervous. He's very sweet now at 7 weeks old, but I've heard Roos can be aggressive and mean. What can I do to raise him right so that he's a mellow, sweet boy when he's grown? I don't want him to be aggressive towards me or my family, but stay friendly. This is my first time raising chickens and they were supposed to be all hens...but I'm not going to give any of them away. I'm way too attached now. Thank you!
