I have 13 queenright Apideas going into winter, mostly doubles which have 8 frames and a feeder but a couple of triples which have 13 frames and a feeder.
I'll post up the losses as they occur.
I added a cup of extra bees to most of them in September, caging the queen for a day or two for safety.
None have been treated for mites. (but in an ideal world I would have done something.)
I looked in a few this morning and the queens are still laying.
Several of them are nice and strong so I would be hopeful of getting a few through to March when there will be a need for a queen or two.
