no it is not from the vent it is from the 'naval', not stringy white/gray (with lots of useful urea to help the tissues shrink), it is definitely organs. i wondered if they might retract- dont know if mesentery is torn.If it's really intestine, and not the waste sack that often comes out of the shell, then no, I don't think your chick has a chance. Infection would kill it if nothing else did first. Is it protruding at the vent? Does it look like pinkish-gray worms, or stringy white-gray-red?
ah, ok , so you are expecting your young girls to have lower fertility? i wonder if that is really due to the age of the hens (i have read papers that says older hens eggs keep fertile longer, but nothing on young ones fertility) or to the experience or status of the rooster. i have real low fertility in my d'uccle pens because of young roosters and older hens telling them where they can go. but in my silkie pen (where you would expect some fertility issues since i dont trim their vent areas) i have a 2 year old rooster and even his 8 month old pullets had excellent-near 90-95% fertility.Clarification: 2 of three hens are pullets. Chances are 66% of the eggs are theirs. They have been laying for a month
