Incubator hatch question

[Samwitch]

Hi all.
I am teacher who has successfully hatched chicks in the classroom in a small digital incubator that monitors temp and humidity. One of our students brought a duck egg to school in his jacket pocket one day. I didn't really count on a hatch, not knowing if it was even fertile...but we put it in the incubator, and tonight, after being away on a field trip all day, I went to check and found a small pip hole. Digital monitor says this is hatch day, so I kind of panicked and brought the incubator home with me. I should have done so before, but I read up and realize now that ducks can take a long time to hatch after first pipping. So... my question is: can I safely take the incubator back to school in the morning if the duckling is still pipping? It's only about a 10 minute car ride. I'd love for it to hatch with my students in the classroom.
Also, I haven't heard any cheeping or seen any movement of the egg, even when I talk to it.
Thanks for any help!

if you think the temp will stay stable then you probably could, just make sure the humidity is right, that is very important, if it's too low the membrane can get stuck to the hatchlings nose and kill it
