I have my flock called the "Chicklets" that are a little over a year old now. Their coop and run is divided and I put 22 10 to 12 week old chicks in the divided section a few weeks back. There have been some escapees from one side to the other but no major blowups as a result. So earlier this week I removed a section of the dividing fence and allowed them to all intermingle. As expected some of the older bird were slightly aggressive but all in all they seem to get along pretty well. Kurt who is my dominant White Rock rooster seems to keep order very well and enjoys all of the new "company". If I tried the same integration with my other flock consisting of only hens I can guarantee that the behavior would be radically different. My hens, although very nice to people, are typical mean hens. I just wondered if anyone else has seen that a rooster mellows out the integration dynamics and drama.
