I checked a hive in my outyard that I put 10F wax shallows on. The super was half drawn out but completely empty. I mean clean. I always see something going into newly drawn comb. I keep going back to a thing one of the old timers at the club said: ‘if they aint putting up honey during the flow you got foul brood’
Hive is a swarm from earlier this year, drew out two deeps and starting on this super.
