I wait until they are no more than slightly cool to the touch, LauraLee. Room temp is ideal, but I rarely wait that long after a shipment comes in. I just don't want to put really cold eggs in a warm bator to avoid condensation.
Often what I get in shipped eggs are detached aircells, which look like an air bubble floating around, as opposed to the round shadow of the yolk itself. You're also looking for hairline cracks in the shell-those I take a quick dip right on the crack in melted paraffin wax, then wrap a strip of wax paper around that area because the wax can make the egg stick in the turner if if comes in contact with the egg cup and melds with it.
