The term for the egg you are describing is boob egg, boob eggs are not unusual and are not an issue, I hatch some every year.
Animals don't kink because they hatch in smaller eggs (the can kink because of temp issue or genetic issue), as for the kink wait until it is out of the egg, you'd be surprised how sometime something that look wrong actually is not (optical illusion because of the position of the animal)
Once it's out you'll have a better idea.
