If your hive box is heavy, you have honey. Depending on how much, if any honey, takes Robo(s) advice and feed sugar syrup.
Robbing will be your biggest threat, but not to bad this time of year. Exposed sugar syrup is asking for trouble, that is why Robo uses a jar feeder through the lid. You can use an in hive feeder so the syrup is not exposed to the outside. Don?t spill the syrup around the hive, this is very important.
This time of Year in your area, feed 1:1 if you don?t already have a hive full of honey.
Blessings
