Nice! I stocked BG March 31st (most around 2" and under) and mine are no where near this size. I have seen a few that are maybe 3 inches but are still to small to swallow a whole piece of feed. They still peck around at it.
To my untrained eye that looks like very very good growth. I'm ready for mine to get big enough to venture out and boil the water at feeding time. Do you have any tricks of the trade you could share?
