My girls have been in their new homes (2 hives) just short of 1 month today. I've been feeding them medicated syrup (fumagilin b & Honey B Healthy) since I hived them but they seem to have been taking it rather sparingly compared to what I see they should take as a new package. They've only been going through about 1 quart a week for each hive. Now, I did notice a good increase in their syrup take the last few days. Maybe that's from increasing numbers from new hatched bees? They have been building up comb on their brand spankin new Pierco plastic frames and the queens have been laying profusely. Plenty of capped brood, eggs, larva pollen, and honey stores. I'm pretty certain that some brood have already emerged too. They still have probably 3-4 outside frames to finish building up, but I added another large super with frames on to each hive today. I guess I'm paranoid about not giving them enough room as their numbers grow. Their feeder is two quart jars each above the inner covers, and they have already figured out how to get up the "extra story" to it.
Was it ok to give them that extra room already? I know conventional wisdom says let them completely build out 70%-80% of the frames before adding boxes. I'd say they were a little closer to 60%, but their numbers are growing rapidly, hence my impatience.
What say you?
