Double nucs already need another honey super! 

Im assuming that there would be massive issues if the entrances were on the same side? I was briefly thinking of trying this in a long Lang

Going to try your double nuc on some mid summer new queens. Learned to not stack new supers on top of queen excluders from you too. I'm 1st year BK. Great info, thank you.

Thanks for the follow up!

Do you eventually separate the queens or will the hive always have double queens?
