Re: hive is bulding a queen cell...what next
Because of the drama package bees go through, they sometimes, as it were, blame the queen, and decide to make a new one.
Very occasionally there really is something wrong with the queen, and you need to let the bees go ahead and replace her. But mostly with a new package, there is nothing wrong with the queen it's just the bees reacting to overall circumstances. Trouble is, how to know. If the brood looks normal and all seems well, your queen is likely OK.
However, if you wish you can choose to allow the queen cell in your hive to take over as a new queen. You don't need to do anything what will happen is the queen cell will hatch, and as per normal procedure when bees are superseding their queen, they normally will not allow the new virgin to kill the existing queen. The virgin will mate and begin laying eggs, and for a time there will be two queens in your hive. But the older queen will gradually be neglected by the bees and over a few months, fade away.
If you really want to, and have enough bees, you can find the two queens and split your hive into two. Around 6 weeks from now you should be able to go through your hive and find two laying queens. Although there might only be one, if the new queen failed to mate, or if the old queen was killed off quickly. But mostly, at that point in time, you would find two queens.
