Promising chicken inactivity

It was above 30 this morning so I went out and opened the chicken door on the coop. When they still hadn't come out at 12:00, 40 degrees, I went out to evict them. The little grey hen was in a nest box - first time I've ever seen one in there - and looked like she was having some kind of difficulty. I set some spaghetti on the porch for the banties, and Grey just emerged and flew up here. I can't wait to go see if she laid her first egg! It's about time. They're nine months old.
