These queens are instrumentally inseminated, and are suitable for queen rearing, research and production hives. Every queen is marked with a numbered disk and has one wing clipped. All of our queens are guaranteed to be fertile and to arrive alive and healthy.
This quote came from the site that I found with a search for
MN Hygienics on Google found here.
Is your queen marked the way they describe on this page?
Has original queen been replaced perhaps?
I read nothing about guarantees regarding gentle behavior on
their website, but what you describe is brutal at best,
perhaps you should contact the supplier and see what they
are willing to do about a replacement.
