Hi Marie and all...
Use two mediums or one deep and put a few frames in the honey in the top box. Leave room in the center for the queen to lay with some pollen frames there too.
You should also feed 1:1 sugar syrup to stimulate the queen to lay heavily, feeding until the dandelions bloom. I would not feed honey unless it is in some frames that you are not extracting, but if you have honey that has crystalized in the frames place it in the bottom box and the bees will eventually move it up as a liquid honey or use it up themselves.
If there are dead bees or mold on the frames the bees will clean them up.
Good luck with your new package bees.
