There seem to be many mixed opinions out there about chickens and cold weather...my question is, if two of my girls (I have a total of six) are shivering inside the coop from the cold (they are mid-molt), do I need to find a way to warm things up in there? Or is it OK for them to shiver? It's about 10 degrees F outside...and 25F or so inside the coop...looking for some opinions!
