2nd year beek here.
A swarm I captured a month ago is mean to the point where I can't inspect the hive. They have also filled 2 brood boxes, all 20 frames with brood and honey and have a honey super on top. I'm considering taking a few frames of brood and putting into my weaker hives. But anyway, I open the lid and they just boil over. My veil and hands get completely covered (thank goodness for gloves) by the time I get 2 frames in. So I figure I need to re-queen to calm them, but in the month I've had them I have never been able to find the queen (partly due to not being able to get far into the hive). I know she is in there laying eggs as I've seen them.
So I'm looking for suggestions on how to proceed. Separate the 2 brood boxes and see which one has new eggs after a few days and spending a long time locating the queen? Contact a local beek with far more experience to come help find the queen and pinch her? Split the hive and let them re-queen themselves? How long should I let the hive go queenless in any case before introducing a new queen?
