It happened to me once, but it was in January, and the temps were in the teens, and at 11 o'clock p.m. I was getting the eggs, and the door handle broke, and could not go out.
I spent about half hour trying to get out, I did have a cell phone with me, but did not want to wake my parents. lol So, I climbed on top of the nesting shelf, knocked out the chicken wire and wiggled through 16 in, by 12 in ventilation under the roof. I lowered the bucket of eggs with the cord, and made a 7 foot drop in the breeding lean-to in the back of the coop. Thanked God, then went to the warm house as fast as I could.
I replaced the door handle the very next day.
