Hey Bees I'm fairly new myself, but I'll take a crack at answering your questions since in the 3 yrs ive been beekeeping I've had just about every hive I've ever had swarm so I'm unfortunately a bit of an expert on the subject. And others can correct me if I'm wrong. First, like you indicated, the first swarm out the door has the original mated queen with it. Therefore, all subsequent after swarms have unmated virgin queens that have just hatched from swarm cells. So by combining them like you did, you threw two queens together in one hive. What iddee is suggesting by telling you to "pinch the queen" is to kill that queen (the one you dont want) before you combine the swarm with the other hive. The one you kill is your call, but iddee is suggesting you keep the original I'm assuming here because she is already mated and accepted. The other queen is unmated, and while i dont know the drone situation in Miami, i know that where im at there are no Drones left to get an unmated queen bred before Winter here. The potential problem with putting two queens together is that eventually there has to be only one queen per hive. Therefore, the bees sort it out by the two queens fighting to the death. And in doing so you run the risk of having the remaining queen get injured in the process, which for obvious reasons is undesirable. And as is already suggested, another problem is that you may be left with the virgin queen in the end. Ill add here that you are probably ok with your original combine (although I personally wouldn't do that again) since I actually did the same thing when my very first hive swarmed and it worked out for me! Do you have other equipment that you could hive that third swarm in? That would make it easier to find that queen to pinch her if you do decide to combine. Or like Bluebee suggests, you could then hive them separately and have yourself another hive. But that too has its own problem since winter is approaching (although in Miami I'm not sure how much of a winter you have) and they need to have built up and have sufficient stores, etc... to survive. Anyway, hope this helps and good luck. You'll get there, just look at everything you do as a "learning experience" and of course that includes those things you do that don't work out so good...it's all a process!
