Newby here and after some advice. Checked hive 8 days ago and all looked pretty good.
Checked agin today (hoping flow frames would be ready to harvest - so close!) and found black, dead larvae in 1 frame. There’s no bad smell, and from my research (read searching google images), I’m not sure what problem it is. Could someone pls enlighten me? (And not say foul brood!)
Not sure if it is relevant but also found a single queen cell on the middle side section of a frame today - they requeened themselves approx 3 months ago when I first got the hive (after a split with a friend)
