ANEL Half-surface Top Feeder with screen. Can be combined with the vertical separation plate ref.AN51100 so you can simultaneously feed three independent colonies without the different populations coming in contact with each other! Can fit all types of hive. If you combine with ANEL feeding cups ref. AN5167V you will be able to fill up the feeders without even opening the hive cover. Worker bees take the syrup both through the open entrance as well as the grid. If you use two feeders for each hive workers will take the syrup through the grid only.
