Hi all, in short I have 3 colonies all with plenty of bees and winter feed, however one is queenless with no eggs or brood at any stage.Due to work commitments I have been unable to inspect for over a month, there are no queen cells so I am assuming that the Queen has unfortunately died. My question is, is it too late to introduce a new queen? normally I would unite with another colony but as all 3 have lots of workers I didn't want to do this if my queenless hive can be saved. All 3 hives are on national brood box with a super above full of stores with no excluder. Any advice much appreciated
Thank you
