I keep my water out in the run so I am not adding additional moisture to the coop. Now that winter has hit in western Massachusetts, I am using a heated dog bowl and refilling during the day as needed. It's been working well. Last night we got our first big snow. The Ladies still came out. But I was wondering if some of the more cautious birds who like to be inside more will come out to get water enough? I really don't want to move water inside. What do you think?
