I had a single hive last year, it didn't make it through the winter, but I figured I had learned enough to double up this year and install 2 hives (which most beekeepers I've heard from recommend anyway). So I got 2 new packages, split the drawn comb between the two hives along with some new foundation for them to draw. Both queens were released by day 5, and I've spotted both of them moving around like they are healthy, but only one of them has taken to laying right away. Hopefully the other one will get to it in short order (I've heard it can be up to two weeks, been 4 days since release already), but the hive with the non-laying queen seems a little slower at everything, from drawing the new foundation to drinking the HBH sugar syrup.
Question is, how far behind can I allow the one hive to lag without the stronger hive starting to make aggressive moves towards the weaker one? Should I switch out a frame of brood right away, or does that run the risk of the weak hive deciding to requeen instead of giving the one they have time to adjust? I'm sort of loathe to try moving brood right now anyway, since the hives are a good 20+ feet apart from each other and the temps are only poking above 60 degrees, I don't imagine that giving them chilled brood would do them much good.
Should I just let nature take its course?
