I just added four new hens to my small flock of four (I doubled my flock!) So two of the four wont go in the coop! It rained ice all day and now its super cold out. They are huddled together on the roost in their pen, and from what I've read here I'm still mot sure whether I should move them in or not. I'm wondering if the older girls establishing pecking order has anything to do with it...suggestions?? Thanks!
