If its been over 24 hours do some research on if you should help or not, otherwise I wouldnt do anything, after reading if they have the external pip, the chick has already penetrated the inner membrane & shell and can breathe. It sounds like it happens alot! Most times they are fine! It may be taking a breather, careful if you help before the blood vessels are dried! Finger Crossed!! this is a "paste" from my incubation record on a thread I started

No pip yet, just a hairline crack all the way around, which doesn't appear to be opened up all.

Thanks for all the informative links.

Started out with I believe 41 eggs.

After candling, that was whittled down to 8 eggs (we only have one rooster at the moment for 33 hens).

I'm getting nervous about the 8 eggs, it seems more should be happening by now.


They're a combination for Rhode Island Reds, Egyptian Fayoumi, Jesery Giants, Amercuana, Red Star, and Autralorps.

Fingers crossed!

Just started aid the hatching process, after reading those links.

Boy is that nerve-racking.


Got a section of the shell about the size of a nickle peeled back and wetted the membrane.

How long before I start picking off more pieces?
