that's a shame lucy but how bad are the cracks? There is a chance to save a cracked egg. Often times it won't make it but if you seal the crack with candle wax there is a chance they can still hatch.
I've had little luck with cracked eggs so far but I have one in my incubator at the moment...
you could take the turner tray out, fit 9 into that and hand turn. Don't fit eggs on the sides of the turner, it will crack them.
Did you read reviews to see if it was any good? It might be or it might not be, I've never seen it before.
You could always store a few eggs for up to 2 weeks in a cool place.
Stick 9 in there, candle them after 5 days and check for progress. If any are infertile (which there most likely will be) then those can be removed and the ones in storage can be heated up slowly to be added a few hours later...
