How do YOU prepare for winter?? My quail cage is 3X6 with a mesh top and floor, it has 1" thick pine on the ends and chicken wire on the front and back.. It is about 3 feet off of the ground.. It is getting cold, quick. My quail are fairing well so far, but it has only gotten down to the mid 40's at night. So, what is the best way to keep them warm? And how do you keep their water from freezing during the winter?
