I visited the hive 24 hours later to see how the girls were settling into their new home. The wood package the bees arrived in was empty so I was able to remove and dispose of it.
I have the entrance reducer in the hive so there is only a small opening for the bees to come and go. This will enable them to defend the hive better until they can build up their numbers. As far as I can tell without opening the hive, they are doing well. I’ll be returning on Tuesday to check syrup levels in the top feeder. I won’t be opening the hive until at least 7 days have gone by to see if Large Marge has been released.
