I know that and my LF did just fine in the last cold snap with temps in the teen and snow on the ground. But the Bantams are just so little...you know what I mean. I know they will do fine and be living a life far safer and warmer than if they were wild birds but ...Just think of the little song birds out there without a coop! Your sebrights will be fine. If you are worried about them, acclimate them by leaving them out longer and longer so they get used to the cold.
