I heard a very unhappy chick thing morning and realized it wasn't in the hatcher. I scrambled over to the incubator and started scanning the shelves for the baby. I must have missed an egg when I moved the last batch of eggs to the hatcher. The incubator is absolutely full, so I started pulling out racks of eggs. I found the empty shell, and no baby. He had fallen from the second shelf all the way to the bottom of the incubator. We named him/her Plinko after the Price is Right game. Plinko is doing fine with the other chicks, but I'll be double checking the egg count from now on!
