After three tries, I got a problem new package to accept a queen. The lady started laying immediately and vigorously and there's a lot of capped brood now.
Oh, and a visible queen cell developing on the observation window side of the hive.... It's not a practice cup, but one over an inch long that seems to be getting a lot of attention. I assume that they are trying to supercede and I'll leave them to it, but I wonder about it only because all the queen cells and practice cups I've seen in TBH are at the edge of the comb, and not in the middle as are more common in the Langs.
Comments? I'm curious.
