Hello all This year I tryed an experiment on the theory of 2 deep brood chambers vs one deep a nd one shallow ( most common in this area). I have already robbed honey from all the colonies with 2 deeps and tomarrow will rob them again. tomarrow I will also rob the colonies with 1 deep and 1 shallow. now for the extra surprise-- all the 2 deeps have 5 to 7 supers on and the 1 deep and 1 shallow have only 2 supers on except one which has 3 supers. This fall the experiment will cease as I will go back to all 2 deeps in the spring. By the way, both ways seem to overwinter here the same, but the 2 deeps build up much faster. Numbers for those needing to know , 7 colonies with doubles and 7 colonies with 1 deep. Al Boehm Columbus N C
