You could also do a combine (newspaper or screen) their is pros an con's, we did a screen combine last year and it worked fine, put the LW hive on top of a strong hive a inner cover with screen door wire over the hole(stapled) or you can just use the screen between hive ,give LW hive a top entrance. Let LW hive sit on top 5 to 7 day's then inspect LW hive, if you don't have anymore double egg cells, the bee's have smelled the strong queen and quit laying, then you just remove screen, the bee's look upset but they will calm down after a little orientation. That was advice given by Mr. iddee, worked like a charm
