Hi I have a first year top bar hive. Earlier this summer I opened up the middle and end bung holes for my hive. I used the entrance reducer on the middle hole and opened up the end hole completely for better ventilation during the hotter months. My question is in preparing for winter (it is getting chilly here in Moscow, Id at night) do I move the entrance reducer back to the end hole and plug up the middle hole completely or can I just plug up the end hole (this has always been the main entrance and exit for the bees)? I noticed that the bees have already started closing off the middle hole themselves and have sealed in the reducer with propolis so it is going to take some work to get it back out of the hole to move it to the end hole. Will it matter if I leave the middle hole open versus the end hole?
