Yes. Hate that but it's extremely useful
Mine all hatched. They just all pipped at the wrong end. I assume @dominiquePL autopsied? She said hers never even managed to pip.
From what I've read, certain types of malposition are more likely to be lethal because the chick is in a position where they can't actually pip. Other types, like the ones I dealt with (head in the wrong end of the egg), can be lethal but more often just make the hatch more risky because the chicks have to do an internal and external pip at the same time, which is hard on the chick and then the membrane is exposed to the air for longer. There's also a risk of the chick hitting a blood vessel, which happened to several of mine but luckily they were ok.
Thank you both for responding! Is there a thread here somewhere for questions if/when the time comes and I decide to perform one?
