Hi. I have six chickens all just about seven months old and doing very well. Getting a steady stream of 5-6 eggs a day. It's starting to get cold here in the Chicago area- dropping below freezing at night. Well past dark when I lock things up- I've just started finding one of the chickens (an Austra White), sitting on TOP of the coop- rather than inside with the rest. I pick her up. Put her at the entrance of the coop, shine a light inside and she jumps up to a roost with her friends. What's up with her staying outside? Think she could take being outside unprotected (weather wise) all night if for some reason I'm not around to put her to bed! FYI: all the girls seem to get along well too. No bullying go on. If anything, the one staying out I always considered the Alpha. Thanks
