I added 20 grafts to queenless hive. After day 1 about 80% took so 16 active cells, had the typical 1/6th-1/4 JZBZ cup full of jelly and drawn out a bit. All looked good. I checked today, day 2 and all but one is left. The rest are bone dry no signs of larva or jelly.
Any ideas what may have caused this. If a rogue virgin or newly mated virgin was in the hive would that cause them to teardown cells? Were all those larva no good, im confused, we are on a big flow lots of nectar coming in.
