In my experience instead of just adding a box of frames take a frame or two brood frames from existing box put them in the center of the new top box and they will start working the second box right away, the brood will hatch and within 3 weeks your second brood box will look healthy and be well on its way for winter ahead
In Scotland I work by frames of brood not drawn frames. Potentially very misleading to use that method. Frames of brood are much more accurate. I add a 2nd BB on 8 frames of brood and they take off. Also in poly hives the frame nearest a wall will be the first one to be drawn out. Bees love to be warm and cosy. ;)
It’s just the opposite in our climate, the bees won’t build the outer frames because it’s too hot ,the bees like to be cooler when it’s 112 degrees Fahrenheit or 44.44 degrees C if you are metric, if my bees don’t have all of their frames drawn out by march they won’t touch the outer frames that season because they want to be cool and not toasty 😝🤘🏼
Good job, just a couple things to help you. You have your entrance upside down, bees should be able to walk in rather than climb over the entrance and should you be using the small entrance on the other side of the same piece until the Bee population rises, new Colonies are not strong enough to defend the large entrance effectively against persistent intruders.
