I raise around 400 nucs for queens usually I can catch 70% of that 400 but this year is horrible about 50% or below. Every queen raiser I talk to said its been a bad year for them also. I run 1200 hives and usually my nucs take care of what I need for queens but I have had to buy queens from different people and they have been just garbage horrible takes on my hives. Theirs a few raisers I buy from that are good but very few . I don't what it is this year but it's just been bad. I would like to hear some input on this and what people have heard what's causing it.
