I live much further south in the mountains of NC, and most of my Scovy's got frost bite on their knobs even my girls got a touch, they chose to be out in the minus weather even though all their doors were open crazy things. Did any of yours have frost bite.Ambi, It has been the worst winter here in Northern Wisconsin that i have ever seen in my 34 years. It hit a low of -55 degrees early February. You have nothing to worry about. lol... All my birds hung in there rather well. They are pretty hardy birds to say the least.
