Hi, one my last turkey hatch, I had a turkey dead in the shell, perfectly formed, yolk sac absorbed, but not internally pipped or external pip, the lid of the incubator was jousled and was slightly open my humidity was low for about 28 hours. was it the low humidity or was it mal positioned? the head was under the wing when I pulled it out of the egg but I am fairly new to hatching so malpostioning unless really obvious is hard for me.
