Very few in my opinion, all queens marked & clipped here. I’ve had a couple of queens balled, possibly due to pheromones when going from colony to colony marking queens as going along? Only a guess???
If any are particularly skittish simply trapped in a crown of thorn’s, marked & then clipped on a subsequent visit. Would recommend when planning to mark queens go to the colony with that intention. Place an upturned roof close by, when found transfer frame with queen to upturned roof.
Did pick up a tip (possibly on here?), when a queen is getting balled, gouge some honey from the corner of the frame she’s on & smear her with it. Don’t be too worried about being careful, she’s gonna die so if you do it it’s just speeded up the process. The bees are then distracted by cleaning/eating up the honey & she’s saved
- it does work
