One of my young barred rock hens (about one year old) is going through a hard molt right now. Her neck lost all feathers and is practically naked. It's December here in Northern California, not that cold of course, but it gets down to 28 degrees F during night time, which means frost on the ground. The chicken coop is built from some thin wood. Though barred rocks are supposedly cold tolerant, i wonder if going through the hard molt puts that hen at risk of being too cold. As i don't have any previous experience with this issue, any comment is highly appreciated.
