Mine are out alot during the winter; but we get alot of -10F and below weather with even colder windchills so they can't be out then. In January, temps usualy hum around 0*F (more times colder than warmer)My birds are never cooped up during the winter, they still free range in the snow, as long as it isn't windy, they roam. I have very hardy birds and love being out even the bantam that is out there likes it.
