Due to increased demand, please expect a 1 week shipping delay. We build these in house and have experienced a large demand this year. The Floating rack Hive Top Feeder is designed to be a hive top bee feeder where you can pour in sugar syrup and the racks will float cutting down on the number of bees that may drown in the syrup, while still giving the bees easy access at the top of the hive but preventing other bees from stealing their food. This is a very versatile multipurpose addition for the hive. This floating rack feeder can be used a few different ways 1. Use both troughs and feed heavy in the spring to get your bees up and going faster. 2. Leave this on all throughout the summer and use for storage, keep a notepad in the trough or use it to collect the bur comb you scrape off the frames. 3. In the winter fill the troughs with sawdust to act as a large moisture absorbent.
