The picture below was taken an hour or two after Three had pushed its way out of the shell. It had just got dry and started to recover a bit when unfortunately its squirmings took it on a U-turn and it ended up headfirst back in the shell again! There were a few minutes when we wondered whether it had a reverse gear or whether it would have to chip its way out all over again. But of course, it eventually escaped as its siblings and Mum moved around the nest and knocked the shell away. Happily, only a dead-end incident, not a dead-ending.
