I apologize if this question is being asked in the wrong forum, but now that the cooler weather is starting to settle in around the Atlanta, GA area, do you think it is time to enclose the girls? We have a 10' x 10' shed we built for our girls (close them up in it at nights) that is open on 3 sides. The back wall is where the laying boxes are mounted. When I say open on three sides, I mean it is double wrapped with field wire and chicken wire. The weather is starting to drop down into the 40's at night, so is it time to wrap at least two of those sides in plastic to keep some heat in? I hate to sound like a worry wart, but I don't want the girls to get cold, but also know that nothing is worse than not having good ventilation since we only let the girls out in the afternoons when we are home.
