Im still new with chickens and this is my 2nd hatch. I've had about 10 hatch already within the las 2 days. Today one zipped about half way or more and it looks like the thin see through membrane is still on a little and there is a yellowish thick ooze coming out on one side. Does anybody know what this is? Im sure its not normal is it? Whats the chances for this little one? Thanks
