I studied intensively on BYC before getting chickens and before building my coop. I then build Fort Knox (our old house) and never had a chicken loss. I read that especially in cold climates, to use a 2x4, laid flat for a roost bar. It is wide enough to allow the chicken to nestle down on his/her feet, keeping them warm in winter. I don't have to worry about sub freezing weather for more than a few days at a time, but I liked the idea of warm toes, and have always used a flat 2x4.
