HELP!! Duck embryo looks like it's stuck to the side of the egg

I usually increase the humidity right away, but since they won't (shouldn't) start hatching immediately, it won't matter if you increase it slowly, or a little late. I've had some chicks surprise me by pipping already as I went to lock them down and they were fine. You don't have to incubate and hatch them "by the book" as long they have the required high humidity when needed and that would be any time from lockdown onwards.

Ok. Thanks for all the info and your advice. It's very appreciated!!!
