A week ago I brought Colony 11 back to my apiary in Headington and combined it with Colony 1. I'm not sure whether to call it a success or a failure but it is now done.
I moved Colony 11 again from its temporary location back to Headington on the evening of Saturday 8th Sept. Early the next morning. I removed the top of Hive A and Hive B. I placed a sheet of newspaper over the crown board. I cracked the body of Hive B from its base and placed it on top of of the newspaper. The hives were now separated but joined.
