Thanks Ken, 

if they rebuild the bridge comb in the brood box I’ll leave it next time. Since the poorer performing hive has some supercedure cells in place I think I’ll follow your advice, the bees know better what they need. Have a great weekend!

These are my first hives, installed 4/18 into 10 frames Langtroths.  As Nucs, both were 5 frames that looked full of bees and resources. Fast forward a couple of weeks and it's obvious that one hive is out pacing the other. Even the landing board activity is much greater on the thriving hive.  But  there's activity (capped brood) in both and since even the pokey hive has about 60% of the first box built out, I added a second brood box to both about 2 weeks ago. Inspected yesterday and the thriving hive is busting at the seams.  The weaker hive is till poking along in the lower box, with very little activity in the second broad box.  Also, 3 supersedure cups have been formed on one of the frames. Found the Queen and successfully marked her with-out any obvious damage.  So if she's a poor performer, should I replace her now or wait for a new queen to hatch out and take over?  Also, since the thriving hive is going gang-busters, should I supplement a frame of bees from that hive into the weaker one until a new queen is established?  Appreciate any thoughts you more experienced guys have on how to handle theses gals. The other problem is that the thriving hive is going nuts with bridge comb and building comb off the surface of the the foundation, sort of between frames. I cleaned up the bridge comb, which gave me a good chance to check larvae for mites.  But not sure how to clean up the off foundation combs. Any suggestions?

Thanks,

Carter
