Although I am very proud of my top bar bee hives, I am not a carpenter. As such, ‘true’ was just an ideal I strove towards when I built them.
The result in Hive #1 is an extra entrance to the hive where my poor carpentry skills have over time created an opening too big to close with propolis.
Although it might be beneficial at times to have a back door for increased ventilation and reduced traffic jams, the bees have to guard it against intruders, which might be a significant drain on resources.
I should probably plug it come winter, no?
