So I've looked through the literature and I found a review article saying all of this and more. It was written by a group of respected physicians from American and French hospitals and it clearly supported the widely held belief that you should drink two to three litres of water a day.
This is a common occurrence to have your brood chamber become honey bound during the main nectar flow. A typical hive body will have a brood cluster in the middle and the outside frames will contain honey. A honey bound hive happens when brood begins to emerge, it is replaced with nectar.
Hives found to have inadequate stores of honey should be fed. Feed diluted honey (80%. honey to 20% water), or sugar syrup at a 2 sugar to I water ratio. Colonies found to have low. populations, (<2 frames of bees), can be combined with strong colonies.
