I took my bees off of their syrup a couple weeks ago after we got a whole lot of rain and all the flowers were in bloom. When I first started feeding them through a top hive feeder there was lots of bees gathering from it and then week by week when I would check up on them I saw fewer and fewer bees gathering syrup (always checked around the same time of day and similar weather). They had stored a whole bunch of the syrup and by the time I had taken the feeder off they had used about maybe 2 quarts in 4 weeks. This is a new hive mind you. So now I have the feeder off was wondering if they should be doing alright? Another question I have is that there is about a whole frame's worth of empty brood. The cells are dark. I was wondering if this is normal and that the bees hav fully grown? Also, there were a bunch of open cells (between 5 and 10)with white pupae in them and I found a couple that had been tossed out of the hive. Is this normal as well?
