Yes that type of feeding activity is common with BG and LMB. I would not harvest my initial stockers unless they were overstocked (to many originally). You do not have to feed them like children (until all are full). It is called supplemental feeding. You may have to harvest some mid sized BG or seine some out.
Are you saying I shouldn't feed BG to satiation, like I did last year with CC?
The way they eat, it seems impossible to feed BG to satiation.
