Internal pipping?

[kaylamlong]

My duck eggs is 21 days old. I have 4 ducks but this is my first time incubating there eggs. I do believe one has internally popped but I wanted to ask some of you experts? Is it to early?

Can't really tell by pic if it has internally pipped or not. But air sack doesn't look drown down yet. But very hard to be for sure just looking at that photo.

No, it's not pipped. They will sometimes push against the membrane.
Duck eggs should hatch around 28 days. You don't want them in the habit of hatching earlier or later or you will then have to deal with birth defects.
