Candle it. Sometimes the chicks don't peep when they're bumping. If the chick has moved into hatch position, is pushing into the air space, this will be very visible when you candle.
Also, do not throw the egg out until you've broken in. Crack the fat end with a spoon or something. Then pick a small hole big enough to get your finger in. First look to see if you see movement below the membrane. If the membrane is white and dry looking, that is good. If it is wet, clearish or bloody, that is bad. If you see a lump under the membrane, reach a finger in and give it a poke. If it moves, put a piece of tape over the hole and put it back in the bator. DO not toss eggs until you are certain they are dead.
I have my fingers crossed too! My two goose eggs from Serjay, which have been hanging out in the waterbator for the last several days, pipped and now one is chipping its way out. I see gray feathers! It's way before I expected, I thought I had plenty of time to clean the Hovabator, air it out, fire it up and get these two eggs in to hatch. Seems these eggs had other plans. Both eggs have pipped and are peeping. One has started chipping. These will be the first birds ever to hatch in the waterbator! This is a big deal. They were not, however, incubated the whole way in the waterbator. I felt it was untried technology and didn't want to risk Serjay's precious eggs. Instead I have my own mutt chicken eggs in there. And now they are about to get trompled by big goose feet! I sure hope so!
