I had 17 eggs that looked like they'd go all the way, out of 24. Everybody hatched but one lone big brown egg, and I swear, I saw NO movement, nothing in it for days. Also, the air pocket had not gotten larger, as will happen when they drink up the remaining fluid before hatching. The last time this happened, the chick had been dead for a day or two - had died near term in the shell. So, I broke the shell over the air sac area on this one, and poked at the chick with a nail. The membrane broke and oozed...rich red blood. I actually poked through twice before I realized that was not fluid from decomposition. Then the chick started moving around. I suppose it lost 3-5 big drops of blood outside, possibly more inside the membrane, before it began to clot. I have wrapped the egg in Cling & Seal, put it hole-upright in an egg carton, and put it back in the incubator with extra humidity. Is there ANY hope for the poor baby? How can it breathe if I have it wrapped up? Is there anything I can do at all? I feel bad. But it hadn't even pipped internally let alone externally, today was the last possible day for hatching according to the calendar, and I'd seen no movement for days.
