I am thinking ahead for the winter and wondering if what I have is going to be ok during the colder months. My 4 girls (Wyndottes) have quite an open run with a roof on one half and boarded up at one end. They also have access to a small building for night perching and egg laying, but not a lot of space for 'hanging around' in. Will my open run be too cold for them during the winter or do I need to close it in a bit more? I am in the UK so dont get the harsh winters that many others have, but it can get down to -10 some years, though that is exceptional. It worries me though that if I box it in more, it will then be too hot come the summer again!!
