Bruising on egg where I can feel duck pipping

[Cowgirl88ss]

Help! First time incubator here... I can feel the duckling trying to pip it’s way out. No visible cracks on outside yet but shell looks bruised right where I feel the pipping. Is this normal? I know their shells are hard to get through. I’ve sprayed them with water and have humidity correct. One hatched already. No others are hatching just a lot of movement

Hard to tell by the pic what's going on...if it's pipping, just let it continue. Ducks usually pip then rest about 24 hours before continuing, it can take 36 to 48 hours for them to hatch from start to finish.
