early hatch questions

[wyochickenranch]

today is day 24 and i have one egg chirped and craked a hole in the shell . they are cayuga ,roan , and khaki . this is the first time I've incubated ducks and it is a homemade incubator but has always kept a consistent 99 degrees acording to the electronic temp and humidity gauge i have ..Should i worry or just relax and wait and let things play out

I am not a hatcher, but have been looking at some of the posts about hatching. Humidity seems to trip people up sometimes - often, too much humidity.

So take a look and see if the Sticky helps. There are also hatchers here, like Lacrystol, Marty1876, yinepu, and several others.
