Queen Introduction---need help
I recently lost queens in two hives due to operator error. I have two new queens set to arrive very shortly. I know for certain that there are no laying queens in either hive, but there may be a non-laying queen that I couldn't spot as I did see an opened queen cell in one and some queen cells that were pretty close to being ready to release a new queen (I removed these).
My question is, if I introduce a new laying queen and there is a recently hatched non-laying queen in the hive, will they kill the new queen that I introduce? There is little chance that I could spot and existing queen due to a very large hive population.
Any thoughts on the best way to introduce the new queens?
