Yeah, this thread was a life saver!
My 2 cracked eggs go into lockdown tomorrow. They're growing and moving lots. Due to hatch Thursday! I hope they hatch.
Good luck with yours.
I just came across this thread. I received a shipment of eggs today and the box was in great shape and 18 of the 20 eggs were in great shape, but 2 of the eggs were cracked. I think I'll try the nail polish thing and see what happens. This thread was a great help!
