I installed my bees yesterday, without a single sting! Both hives have the division board feeders. I used 5 lbs. of sugar into 2 1/2 quarts of water. It made close to a gallon of syrup. Each container got half, or 2 quarts. I floated a styrofoam "raft" in them. My question is this: I understand that you are not to open the hive for several days. So is this enough food for several days? I regret buying this type of feeder (I think?).
