2 and 1/2 month old colony wont use lower box
i installed a package in 2 mediums on april 13. they drew out 5 frames pretty quickly. i gradually moved frames around and now have 8 frames. they are building in the top box only.there are plenty of bees on these frames. should i reverse the boxes to try to get them to work on the other box? should i still be feeding them? i was going to wait till the end of the summer before resuming feeding. i haven't checked on them for about a week and a half because of the extreme heat the last week or so. also, i have the one piece plastic frame/foundations. i don't think 1 medium is enough for them to winter over in.
thanks for any info.
