troubles hatching call ducks.

[smalltowngirl33]

HI

I have call ducks and we have had lots of trouble with the sucess of hatching tryong out what we did wrong.all the eggs i candled are fertile.when it come to hatching I have one or two that hatch out on there on all the others dont make it out.I have read they are bad for breeching. I found alot of the ducks suffacted in the egg. I found an artical telling me to make an air hole so they can breath then they should comeout the rest of the way.had some live and some still die cause they get stuck in the egg,.I even boosted the humitiy.Im at a loss on how to get a better hatch rate ....can some please help????

are you misting and cooling the eggs from days 7 and up. I used to have the same problems until I started doing that. Also, are you hand turning or using a yello? turner.
