Two new hives that I started May 1st. Both hives have their bottom hive bodies full with a second on top that have 6 of the frames drawn and full of brood. They both have been eating between Â¾ and a full quart of 1sugar to 1 Â½ water a day from Boardman feeders and look about equal strength. Last night I refilled like usual to return Â½ hour later to an all out robbing war on hive #2. Fighting like hell on the landing board etc. They devoured 1/3 of the jar in the time I was gone. I pulled the feeder and reduced the entrance to a few inches. I returned again in a half hour to find the hive was returning the robbing favor on Hive #1 so I did the same thing and everyone quieted down in about 20 minutes. I left the feeders off until just before dark and opened the entrances back up. I know Boardmanâ€™s can induce robbing but this is the 1st problem Iâ€™ve seen. Should I add an empty super and feed through the top cover opening or is it time to cut them off sugar completely? I already plan on stopping when they get the other 4 frames drawn out and start using them. We have a ton of clover etc. going at the moment.
