I am baffled, today is day 21 and my first of three eggs was piping when I saw it four hours ago. Just checked again and the chick is GONE and so is another of the eggs. I had just separated mom and eggs from the flock with chicken wire this morning when I heard the cheeping and saw the egg was cracked. Now there is one egg left under the hen, and one empty shell which looks like the chick hatched out itself (this the shell from the one that was piping). The other egg is missing entirely. The leftover shell is crushed but looks like the chick zipped itself out. There was a little gooey mass still on the inside. Can anyone tell me what happened? Is it possible that the chick is up under the hens wings? I had her walk off the nest and didn't see anything. She is not dirty like she was partita massacre.... Please give me some advice, this was to be our first chick!
