I wear my boots if I'm in their run or their house but they free range in our yard and feild and honestly even in the cold I'm the crazy girl wearing sandals. Unless there's a lot of snow on the ground.
It's been cold for almost a month. I'm talking like 0-20 degrees and my leghorns lay almost as well as through the summer months. They're great layers. But they'll peck the **** out of your toes if you're outside in sandles.
