Backwards

[TicketyBoo]

What would make a chick hatch backwards in the egg? It's butt was pushed into the air cell (unless it pipped through then rotate completely?) and its head was at the narrower end of the egg. Obviously it died because I was trying to be good and stay hands off. It was very determined to hatch by the sounds of it last night but died early this morning.
What did I do wrong??

As the egg develops, the embryo lies "across" the egg. Once it gets too big to fit that way, it turns with it's head towards the highest point in the egg, normally the large end, where the air cell is. For a short time it can turn if needed, but soon becomes too big to make the turn and is then committed. Short version; the egg was either incubated upside down, or due most likely to poor egg shape the "small" end was higher when the little guy turned. And sometimes it just happens.
