I have 2 top-bar hives, started last Spring from swarms. One produced more honey than brood and the other more brood than honey( I transferred some honey from the rich hive to the relatively honey-poor hive prior to winter). They both appeared healthy going into winter. The one with more brood survived our unusually bitter unrelentingly cold Colorado winter and is now vigorous, though a bit low on honey stores. The honey-rich hive is empty--no dead bees, still with 4 or 5 full combs of capped honey, some part honey/part empty combs, and empty brood combs in the middle (side entrance hive) with just a few scattered capped brood cells.
2 questions: 1. Is this CCD? 2. Is it safe to transfer a comb or 2 of honey to the live hive or could there be some disease vector in the honey?
