When to pull unhatched eggs from Muscovy?

[katlovesaandw]

Broody Muscovy.
Went and bought 6 fertilized Muscovy eggs from a local farmer.
She kicked out 3 by end of Week 2.
3 left.
Yesterday was day 35.
She hatched 1 duckling on Sat. morning. We pulled it to put in brooder as our flock is not baby-safe.
2 eggs left.
I checked this morning and nothing. Still 2 eggs.
Today is day 36.

How long do I give them? Or pull them tonight?

Our yard debris(where I can put dud eggs) goes out in the AM so would prefer to get them out IF they need to be pulled.
If I should give them a few more days, I can though.

This is our 1st time doing duck eggs.

sorry for the late response, for future reference wait for about 39 days, day 37 is when most hatch but its best to wait till day 39 to make sure they have enough time just incase
