Call Ducks

[nikkiru]

HELP> This is my first time hatching call ducks or anything for that matter. Today marks day 30 in incubation. We got 1 of 5 eggs hatched just over 48 hours ago. Then came 2,3&4 24 hours later. Last egg has piped maybe tried to zip a little over 24 hours ago. I noticed slight movement in the egg last night around 11pm. Today on day 30 and 24 hours later I have seen no movement and no more progress. The first duckling has been in incubator now 48 hours and I know I need to move them to their new home but have been told that if I open the incubator that I will or could possibly shrink wrap and kill final egg #5. So here is the question.
Do I wait it out or can I take ducklings 1-4 out and leave #5 in there or final question do I remove babies and assist in final egg and hope its alive?

TIA

I added a picture. The humidity is at 65% don’t worry the humidity lols worse only because the other babies are moving around more today

Call ducks often need assistance hatching due to their short bills (unable to position properly to pip/zip). Lots of threads and youtube videos on this topic: https://www.backyardchickens.com/articles/assisting-call-duck-hatches.76507/

I also regularly open the incubator really quickly to get dried chicks out and have not had issues as long as it's quick and humidity is adequate.

I suspect this chick may need some help.
