Two points raised by this post and your last.
This one first. So, apparently the volume of drones I will be sending out will be too many? Now, in terms of 'drones coming from Down Ampney' what exactly is different from before? Despite your repeated assertions to the contrary, the actual volume of bees on that estate will not be seriously greater than before. You have been told repeatedly that the total involved will be scattered on a significant number of sites. Fwiw I generally operate in groups of 20 to 24, though this can rise or fall in relation to available forage.
One further point on the bees that will be with them. It is part of my spec that any packages MUST be drone seived. No drones at all allowed. Thus the package workers will die out in a short time and leave no genetic mark whatsoever inthe area.
Secondly you have re-erected the straw man of New Zealand bees. Standard New Zealand bees have just about zero significance to this thread as NONE of these are involved. The imports everyone has talked about from there are Italian stock, and to be honest the reports of bad wintering performance, too much brood out of season, esp late autumn, and very little honey are just about spot on in my limited experience of these. However this is not the bee under consideration, so please, desist linking them.
Off at 4AM, and will be on site at Down Ampney tomorrow, Hereford on Saturday, and giving a talk in Herefordshire on Sunday, so will be off the thread and unable to answer questions until I return on Monday.
