The pen I keep my Bobwhites in is divided into two sections; a fenced in outdoor area and a sheltered indoor area in the barn. They almost always sleep outside and I rarely see them in the inside section other than right after I give them new food and water in there. They've been in this same set up for several months now and have been fine but now as the weather is getting colder (40s during the day, 30s and sometimes 20s at night) I'm worried about the potential harm the freezing temperatures will bring since they're out in them all night. I'm particularly concerned since the forecast lists every day for the next 10 days as solid rain with strong winds and the temperatures dipping as low as 27 at night. They've done alright in rain before but it hasn't been this cold before. Should I be concerned or will they do alright in conditions like that? Like I said, they have the option of going inside to the dry indoor area at any time but they rarely do. I could herd them all in there and close them in so they're stuck in the indoor section until the rain stops but the indoor area would then be pretty cramped which may lead to them being worse off than if they were outside in the rain. Any advice?
