Boardman Feeder Cap
Simply screw on a regular-mouth mason jar filled with sugar syrup (not included) and install into the entrance of the hive.
These feeders are easy to monitor as they are visible from outside of the hive. The Boardman feeder comes with the plastic base and a perforated metal feeding cap. Sugar syrup is an excellent supplemental feed for newly developed colonies.
Hint: Keep an extra cap with jar to quickly exchange feeder jars when using a Boardman feeder.
