Duckling struggling to hatch
If there is blood it is not ready to hatch.
Leave it alone. it will hatch when it is ready, or it will not hatch ever, that is natural selection.
Peeling it out will not help at all.
See the duck did not need a midwife after all! Grats..
Your Welcome,,,BUT please do not tell anyone I gave you advice that caused a Duckling to hatch. I have a reputation to maintain and as we all know there are too many ducks in this world already!
Have a good one.
