The chickens here have never been resticted from free ranging. 20 below zero, the coop doors are opened. 26 inches of snow, the coop doors are opened. Sleet, hail, freezing rain, doesn't matter. The doors are opened. What they do is their choice. Missouri has "real" winters?Very neat! I would love to see a chicken riding a sheep!We get very little snow here. It may snow 3 times a year and no more than a foot each time. The coldest I've ever seen it get was 5 degrees and that was 1 night I believe 2 winters ago. We do have ice storms that close the schools down and can be a concern. There are maybe 5 days a year that I don't let the chickens free range do to the weather. I've considered moving to colder states and specifically looked into Colorado. Now I'm looking into Missouri and it looks like the one. It's colder than Arkansas but not extreme. It should be a fun experience to see how the chickens do in a real winter!
