I received five (marked) queens last Wed. and put them in 5 frame nuc's Thurs. with pulled brood frames (capped) from some of my strong hives with nurse bees. I checked them today (monday) and all were released, Found two queens on frames with their circle of attendants:thumbsup:. Found one with her attendants and a supersedure cell on the next frame over (capped?) and did not find the other two queens, but did find three capped supersedure cells in the middle of one frame in one nuc, and four supersedure cells in the other nuc (two frames had two supersedure cells each):shock: These frames (3 with brood and bees in each nuc) did not have queen cells or cups when i pulled them, i looked them all three times to make sure i didn't take the donor hives queen and almost all the brood was capped. Is it possible that they built queen cells and capped them in 5 days?:???: I've been at this a long time and never had this happen this quick. Jack P.S. i pulled these brood frames with bees last Wed. and they set in the bed of my truck over night,i set the nucs out and put the queen cages in around 11:00am the next day, Thurs.
