Thanks Guys
It looks like an early but tbh it was due yesterday and all my previous batches have been a day early so it's 2 days later than norm. I just had a look, it's very very weak, I've managed to detach it from the egg shell (there was only a little blood). It still has cord attached but I thought it was more likely to have a hernia with half a shell attached. It's still very wet so if it's still alive in the morning I'll shift a lizard and put it under it's heat lamp instead of the one I use for day olds., it worked for some ducklings I hatched. Looks like both it's eyes are still covered though. i'll keep you posted.
