Honeytaker, that is sad, it is sad to lose a colony/ies. But things do happen. It always makes us wonder what has happened, was it something we could have intervened with, weather, who knows. I have lost lots of colonies too and it always makes me feel very troubled to say the least. So still, keep that chin up.
P.S. Please take off the cap locks, the large letters are hard to read and cap locks is indicative of someone shouting, pleeeeeeze, no offence to be meant, just hard on the eyes. Good luck with the rest of your bees (do you have other colonies, by the way? tell about it to us). Have that great and most wonderfully awesome day, with beautiful health. Cindi
