What possibly could have went wrong.

You can open the incubator to remove dried ducklings, but you need to be quick, so you don't lose too much humidity. This thread:

https://www.backyardchickens.com/t/594278/thread-formerly-known-as-hatch-day-is-today/0_30

has some fantastic info in it, but it's yeah long. What I did was search the thread for specific posts to get answers. When you have the thread open, look under the title, you'll see "Search This Thread", click on that and type in keywords to narrow down the posts with relevant info. Good luck with your hatch!

Thank you for the link, I will look at the thread.

Not all duck eggs are created equal, some need 35 days.

Others only require 28 days to hatch.

I knew this but they must not. These were Pekin Duck eggs.

With not knowing what they were doing I can only guess to what went wrong. In this case I would have to say it was completely human error.

Once I hatch my chicken eggs I am gonna try to hatch some ducks. Thank you everyone. You have reasures me that I am not an idiot and I am correct on the humidity needs to be watched.

IMO, all species of eggs have an optimal humidity, temperature and a specific duration. The duration can definitely vary depending on many conditions.
