Its early August in Oregon. I have 7 hives placed this year on April 6th. All 7 hives are currently 3 box hives. 4 of the 7 colonies have filled the 3rd box with comb. Here is my questions.
Is it too late in the season to be adding a 4th box?
If I add a 4th box now, should I remove it later in the fall for the rest of the winter?
Appreciate an input from your experiences.
