Checked my bees this year and found one hive out of my 2 is completely empty. There is no honey, bees nothing. They just simply disappeared. They were very stong and healthy over the summer ( installed in April of 12). There are no bee bodies. Is this CCD? Is it ok for me to install a new package of bees using the drawn foundation? I am planning on putting in 3 new hives this year. Should I give all 3 some of the drawn comb? Any worry of disease?
