When sorting through brood combs to replace poor ones, I have noticed that I have a number of one-piece Piercos that are unsuitable for brood. I.e., it is pretty obviious that the cells on one side are deeper than the cells on the other, and during the active season I have seen that the queens will sometimes only produce brood on one side. This breaks up the continuity of the brood nest.
I wonder if anyone else has ever noticed this. FWIW I have 10 frames in chamber when drawing and also for regular brooding, w/ end bars tight together.
I guess the foundation part of the frames bowed, or else was not straight when I purchased them. I save these aside as honey storage combs, and keep them out of the brood nests.
Otherwise I found good acceptance for drawing of comb and like the Piercos, if they are straight. They maximize the number of good worker cells available in a brood comb.
Thanks for any comments.
