I am still a greenhorn here... only my second year as a beek. Last year I was advised to use a frame feeder with the pros touted as less chance of robbing, easy access for the bees, even helping maintain brood temp in winter(not sure of that one). Anyway, I lost my one colony overwinter. This spring I installed a new package and pail feeder. It seems to work very well. I don't seem to have the dead bees I got with the frame feeder. It's very easy to get to without interrupting the hive. Last week I started a nuc and put the frame feeder in it.... 7 days later it already has many dead bees in it. Long story short, is there a disadvantage to using the pail feeder vs. the frame feeder? What am I missing?
