I have a hive that did very well during the spring. 1 deep and 1 med for brood. added a plastic queen excluder and then started adding honey supers along. took the honey off today to find the queen has been going through the excluder back and forth laying up the center through the honey. wonder laying patterns frame after frame brood and eggs. dont get me wrong , very happy with the queen but how is she passing back and forth through the excluder? is it the plastic excluder or is this common? Can it be stopped? do the metal excluders prevent this?
