Today is the day my mallard duck eggs are supposed to hatch. Right now I can hear one of them peeping inside the egg. There is no pipping yet at all and the peeping is pretty loud, it can be heard outside the incubator into the next room. Is this normal? I have never run across this before but this is only the second time I've tried to hatch ducks. I thought they couldn't do that until they were out in the air. What do I do if anything? I would really like to save these babies if I can, as they belong to a duck I just lost, but I don't want to start messing around if this is normal. Yesterday I found one with the bill just barely sticking out of the shell and it had died. I really have no idead why. It looked almost as if it just couldn't do anymore.
