Hi, I'm new to this site. I have 11 white doves that have been inside for over a year. It was time for us to move and them to have more room. I recently moved them to an outside chicken coop. They have been outside for over a month. They seem to be doing very well. My main question today. We are experiencing an early cold snap. I live in Kansas and it usually isn't this cold until late December into January. Definitely not in the 20's in October. I have added a light to their coop, but am worried this is not enough for them. They made it through last night. Should I close them up in the barn part of the coop for the night? If I put plastic around the cage part of the coop, how does this work for ventilation? Any suggestions will be welcome. Thank you.
