Mine don't free range. Their run is partially covered, but snow still blows in in some areas. If it's not too bad, they'll come out and stay in the snow-free areas. If there's been a storm that has blown snow everywhere inside the run, they won't come out. In that case, I go and clear the snow, and spread a bag of dry leaves on the ground (I bag and save a lot of leaves in the fall, to use throughout the year in the run). They LOVE walking around and scratching through the nice, fluffy, dry leaves! They'd really rather be outside, so they appreciate the carpet of leaves and always come out onto it, no matter how cold it is otherwise.
Here they are today, in single digits Fahrenheit, enjoying the dry leaves and a nice treat of warm mash (their regular crumble mixed with hot water until it's clumpy in consistency).
