Re: Queen less topbar
If it is a strong hive I would leave it until spring then requeen it. I had a TBH last year that went through winter with an utterly useless queen that would not lay much at all. they made it to spring and the new queen managed to build a population that filled the entire hive with comb and honey. I will take whatever honey they have next spring at the first sign they are foraging.
