We are finally dipping below freezing here in Texas and I have a question about sleeping arrangements. I have a combo coop/run. The whole structure is about 8x10. There is a 4x8 'loft' area where the hens roost at night and there nests are there as well. I have a roost on the opposite side that is open (well, covered with hardware cloth instead of siding) I have two young hens who have always slept on the outside roost. Will they go in and sleep with the others if they get cold? I've included a picture of my coop to give you an idea of the setup.
