I live in NH, and of course the weather doesn’t know what it’s supposed to do. Last Sunday we had a snow storm. And today it was rainy and close to the 50’s. My chickens got wet and tonight it’s supposed to get down to about 25 degrees real feel about 18. My question is should I be concerned for them freezing or will their body heat dry them and keep them warm? What can I do to dry them up a bit? If needed
