When is the latest you have ever hatched duck eggs?

Hello all. I am incubating duck eggs and it's the end of the 28th day and I don't see any movement. I was wondering when the latest you ever hatched your duck eggs was?

Thanks!

I have not hatched eggs but I have seen that it can take over 28 days. Muscovies generally take longer, and sometimes fluctuations in temperature and humidity can cause the process to take longer.

Hope a hatcher checks in soon.
