Very sorree. rather than a sarcastic "As per usual, just the barest of details" would have been sufficient.
Only stating fact. Not sarcastic - the truth. Usual problem in helping anyone, is that; not having anywhere enough information. Hope others read and take note, too.
I'm not totally dumb, just new! Are you suggesting I said that? I think not.
One of my questions was: Results of mite drop check? Results of drone brood checks?
Until we know what size the colony, its likely make-up, age, etc, we have no idea as to what checks you might or might not have done. Nuc - not likely to be much drone brood unless it was a nuc thrown together by the supplier immediately before despatch (may have a lot of varroa in drone brood). Full colony - you should have checked the drone brood when received.
I can understand you may not have known anything before you sourced your bees - it happens quite often these days, but by the same token, you may have studied deeply but that was not indicated by the nature your post.
I will reply in my simple blunt way. You can take on board my comments or ignore them. That is entirely up to you.
Now the aforementioned may well be able to offer some more sound advice, now they know what they are dealing with.
