They won't hang with the other roo and his girls. They don't fight or anything. In fact they will even roost next to the others. As soon as I open the pop up door, all my original chickens and roo, go outside. Then the other roo and his girls jump down from the roost, and eat like they are starving! They NEVER come out! It has been 2 weeks! HELP? Just a note, I am able to pet and hold ALL of my chickens. The rhode Islands are a little apprehensive, and I have seen them go after the new girls, when I have FORCED them outside.
