The split I formed on 30/4 (Hive 4) appears to be on the road to success! I did an inspection yesterday (14/5) and found at least 2 capped queen cells. This means two things. The split contained eggs and the old queen remained in the parent hive (Hive 2)! Just what I wanted! In a couple of days there should be a new queen in residence. Give it a couple more weeks and with luck she'll be laying! So no further inspections until early June!
I did go through Hive 1 but this was quite feisty and I got stung a couple of times. It is bursting with bees and looks ripe for a split, but I didn't do this as I felt they were not very accepting of me. I will go back wearing more protection - layers on my arms!. I did however add a third super - bottom supered.
