Last spring I acquired 3 chicks and 1 Indian Runner duckling.... well a couple months later I find out that all 3 of my chicks are roosters... I wanted the chickens for eggs so naturally I had to come up with a new plan. I found fanastic homes for the roosters and got 3 more chicks in hopes of starting over but the question I have is when its time to replace the roosters with the new flock, will the runner be aggressive towards the youngins. The runner is a female and has never been aggressive towards the roosters but she also grew up with them. The new chicks are just over 4 weeks now so I still have a couple of weeks before they come out of the brooder. Any ideas on how to integrate them smoothly would be much appreciated.
