Advice needed please--egg in the process of hatching outside, but getting down to the teens tonight

[MS_pond]

Question: Should I leave the nearly-hatched egg with momma duck in this cold snap, or put it in a yogurt incubator inside?

Details: I have a muscovy hen sitting in the duck house with one egg in the process of hatching. It externally pipped almost 48 hours ago and peeping inside. The thing is that it's getting down to the teens tonight and for the next few days (mississippi). I was really hoping it would hatch before the cold hits but at this rate it doesn't seem like it will.

If it hatched before tonight I was going to move mom and duckling into a big brooder in an insulated part of the barn until the cold snap passes, then move them back to a separated space in the duck house. I'm afraid if I move them now, mom will stop sitting the egg, as I've tried that in the past with her.

Should I leave them be, or should I take the egg in and even assist the hatch? I don't have a proper incubator but I do have a yogurt incubator with precise temperature controls. And I can put a wet paper towel in there for humidity.

My understanding is that with incubating eggs, at this point (48hrs after external pip with no visible progress), the egg can and should be assisted. But the egg has a momma duck so idk.

Thank you for reading.

I'd personally would leave it with her, but I've never had anything setting in those temps.

I would leave the egg with Mom. She will keep it at the proper temperature and humidity. Both before and after hatch. Muscovy ducklings take longer from PIP to hatch than Mallard derived ducklings.

I have had chickens successfully hatch with temperatures in the teens.

We had our runner ducks lay and hatch (started hatching last week) We had a couple -10 random nights and they did ok. We have 2 heat lamps. Taking the baby out to a brooder now because I just learnt ducks may not be good mama’s. Lost 2 out of the 3 within a couple of days.
