Hatching issues

[Deej211]

I had 2 arucauna eggs in the incubator, both pipped internally 1st one needed minimal help out of the shell 2nd one if i hadnt broken the shell and had a look would have been shrinkwrapped despite enough humidity to mist up the bator, hygrometer is telling me its around 70%. she had a completely white membrane almost as opaque as the outer one. i removed a fair bit of shell and just enough membrane to get her face out and wrapped her in a wet cloth and put her back in the bator to finish absorbing the yolk. im stressing that she wont make it. would reducing my chickens calcium intake make the shells thinner? they have extremely hard shells.

A bigger majority of shrinkwrapping, I believe, is caused by the air cell growing too big during the incubation period than anything at hatch. What was your humidity for the first 17 days, and has your hygrometer ever been checked for accuracy?

The feed question I will let someone who knows about that answer.

Hi. I live in the tropics the humidity in the air here is over 50% for most of the year. And there was enough humidity in there to have condensation. the air cell was bigger on the 2nd egg but not excessively so. My hygrometer hasnt been checked as yet though.
