Delayed duck hatching- is this internal pipping??

[Carebear921]

I have an egg that's technically on day 30 (not a Muscovy) while the other two hatched on days 27 and 28. I've included a video to make sure what I'm saying is internal pipping actually is. Because he's so late should I make an air safety hole? Thanks!

It is an internal pip - if you haven't seen an external pip for somewhere around 16 hours after the internal pip occurred, it would not hurt to add a safety hole.
This article covers most of the information you will need to do so safely:
