I put a new queen in a hive today to replace one that died. I just installed these two hives last week. I did my first inspection on Sunday. The two gallon feeders of sugar water still had quite a bit. Today when i opened that hive, the water is really down just from Sunday, and the pollen patty I put in is also nearly gone. I didn't mess with the other hive so soon after the first inspection, but I'm guessing it's in a similar situation. I'm going to mix up some more sugar water tonight and take it over tomorrow, and get a couple of pollen patties in case I need to replace those.
