We have an EE hen and a barnyard mix roo who are the same size as our smallest hen in the main coop. We've had them in an adjacent pen so they have seen/gotten to know each other (in fact, they were in an adjacent pen from the time they were out of the brooder). The younger hen/roo we want to put in with the main flock so we can have the other pens for the cochins we will be breeding. Every time we put them in with the older ones though, they get pecked and hassled. No blood or fatalities but they go after the rooster every time. They are ignoring the EE hen for the most part, and she's just hanging with the barnyard roo. The big roo is pretty much ignoring them both unless they run straight at him. We have a second food and water bowl in there so they can get to it. My question is how long should we leave them in there before we say it ain't gonna work and yank them out? Its the first time we've had to try adding new ones in, and I have no idea how long I should give them to establish their pecking order. The two newbies are so nervous in there and I don't want them totally stressed out.
