We let my broody hen sit on bantam chicken and duck eggs on June 8. It has definitely been 21 days but no chickens have pipped; however, my lone duck egg has pipped yesterday around 10 pm. Now the the pips outer shell is gone but the membrane is still there since the around 1 this afternoon. Is this normal to take so long and hatch so early? I can hear him cheep and he moves like crazy. We also have a humidifier going on in the room to make it more humid. I have read a bunch of places that ducks take forever to hatch. Is that true? Also, they need help usually, I think its strange that he pipped so early. Perhaps he really is a chicken and the eggs I bought were mislabeled. On the 19th day the broody hen's (Paula Dean) water spilt in pen. (i found it early) On another post, someone told me that the eggs might hatch a little late. ???????
