Agree with apis completely.... A little time and experience, including theis experience, will be beneficial to you in the future. If the queen is not laying after a week I would call who ever I got the package from and get another queen. If they apear to have nosema, I would get another package etc...
I come down on package bees pretty hard at times, but they DO have their place. I buy packages and let them get started and growing, then replace the queens with local / resistant queens from proven stock. I will often put the package queens in nucs that are well managed to keep them from making drones and see if they will overwinter.
Often package queens are superseded, and I let the bees replace them, but still replace the queen later when she is laying well... so dont write off packages, just be prepared to deal with the troubles they can cause.
