"I have thought of maybe building a telescoping wooden insulated top but will wait until I see the result of the simple changes I made." Keith: I have tried and use the insulated telescoping top and it works fine. Tried two winters now and on it's third. Checked them today and they downed a gallon of sugar water in 5 days. Tried with and without the vitamins and electrolytes and with the Honey Bee Healthy. Twice the consumption with the additives as without. Very Strong hive! I have others in a row that do not have the same top as a test for this winter in the bus. Installed the Kona Queens today as well. Another test is fall/winter requeening. Half the hives are poly and half wood. Also two insulated wood hives.
