What’s going on inside this duck egg?

If you see a circle on the egg in the video thats because I marked it for turning purposes.

It looked like this Wednesday (check inserted photo below) and now it looks like this in a video yesterday (July 1st).

How long have it been incubating?

Its been incubating properly since maybe June 25. Its been developing slowly because I didn’t have an incubator and had to make one and now I finally have a thermometer/ hygrometer duo which shows humidity is very low. I don’t think temperature was really ever an issue but it definitely could’ve been.
