Re: Split gone wrong?
If the queen is in the donor hive, most of the bees you moved to the split will return to the original hive.
I'm guessing the idea is you want the split to make a new queen? If so, they will be struggling because of lack of bees. What you can do is swap the 2 hives around so that when the bees from the donor hive return to their normal position they will join the new split. You may need to give the split a new comb with eggs.
All this is leaving aside whether you should actually be making a split at this time of year.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
