Annette, I have been so busy I haven't had much time on the forum. I hope all goes well with you, getting another package is probably a good idea. Those darn laying workers, eh?
I don't think that this has been talked about yet. When you are ever shaking a frame of open eggs, larvae, you must be careful not to shake too hard. The larvae can be dislodged from the cells. I remember Finsky talking about that, remember him? Too bad he isn't here anymore. I recall him speaking that he dumped out a bunch of larvae, so when you shake, be firm, don't shake the frames a bunch of times, just one good kind of shake bump, can't really define it much better.
The best queens are made from eggs that have hatched and are no older than 36 hours old. If you see larvae, they are getting a bit old to make excellent queens. That is why it is so important when wanting to give the bees the means to make a new queen to try the best to include eggs. No doubt there will be some eggs when you can just barely see the larvae, but keep that is the back of your mind.
Good luck girl, you are doing just fine, you are learning so many things and taking it all in stride, have the most beautiful and wonderful day, successful thoughts coming from me to you. Cindi
