First year of beekeeping and was wondering about robbing and how one should react. It appears most of the nectar flow is slowing down this time of year in addition to the lack of rain and high temps. I have noticed bees rolling out other bees from the hive enterance as well as flying off with two bees tangled together. I have reduced the hive enterance to about 1/3 open. Is there anything else one should do at this time? I have been feeding the weak hive and have just started feeding the strong hive again with the lack of nectar flow. I am using a hive top feeder with a screened inner cover where bees can only get at the feeder through the hive enterance. I have read where robbing can wripe out a hive if not helped. Don't know at what point reducing the enterance or closing it would be called for??? I would appreciate any thoughts from those who have more experience with this issue. Thanks.
