I have just finished the covers for the windows on the boxes and posted pics. I had an old campaign sign that I cut to add some insulation to the window before putting on the cover as well. I will attach the covers by using metal latches.
I also have put two coats of linseed oil onto the hive. Linseed oil is preferred in natural beekeeping as it does not contain harmful chemicals yet will protect the hive from the weather. Pics of the hives post-linseed applications will come soon.
