With all the wet weather, one of my hive boxes seems to be warping a bit. It just so happens it is the top one containing the colony! As a result, there are now gaps above and below the observation window where bees are now coming out to explore the space between the window and its wooden cover. This essentially renders this window inoperative.
Any thoughts on ways in which I can remedy the situation, other than hope it goes back ot normal when things start drying up?
