Help! I have a duckling that is stuck at the wrong end. Veins are still visible some are thick. What can I do?

[New duck mommy 2021]

Chick's at the wrong end have no way to internally pip and die from suffocation. So knowing the correct day of development will help to save the chick.

Some make a bruise and at that point we make a tiny safety hole in the centre of the bruise and leave baby be for 48 hours then start to candle to see how things look
Other babies make their own external pip and hatch on their own just fine
