do duck eggs take longer to zip than chicken eggs or are my ducks in trouble? i have one that pipped around 36 hours ago that has only zipped about half way around the egg and the other that pipped about 20 hours ago has only zipped about 1/4th of the way around.
the other eggs havent even pipped yet and all had good movement right before lockdown? today is hatch day? any help would be greatly appreciated. thanks
