Do you keep your chickens locked up in the coop when it rains? I mean, rains for a long time as in days. Reason I ask is that my 6 week olds have a nice dry coop with food and water but they are wading out in the cold mud instead. I'm a little worried about them being all wet and cold. It's been in the 100's for months and now suddenly it's raining and 55.
