What was your humidity like? In my first hatch, my humidity was too high and they grew too big to hatch... now I do dry incubating around 25 to 30% humidity and hatches have gone great!
I have read a lot about the dry hatch method. I am thinking I will try it next time I use the bator.....
Do you have any problems with the membrane drying out and chicks sticking to the egg? Of not being able to unpeel themselves?
Thanks
