I just had to share this with people that I knew would appreciate it. I have a three month EE hen and just yesterday added a younger (6 weeks or so) Barred Rock hen (well, we hope it's a hen!) in her run and coop with her. Since the temp is supposed to get pretty cool tonight I wanted to bring the little one in for the night. When I went into the coop to get her, they had already settled down for the night, I couldn't find the little one, but I heard chirping. So I got a flashlight and found my little BR under my EE's wing!!!! She was keeping her new friend warm! When I picked up the BR she was nice and warm, the EE was doing a great job! I didn't like taking her out, but I want to be safe with the cool weather. I am new to keeping chickens, so I'm not sure if this is common or not...but it is OH SO SWEET!!!
