How far along is this egg?

[janiedoe]

One of my broody hens was sitting on 3 eggs. She hatched one 4 days ago. When I checked the other two eggs (both duds) today, I found an additional egg. Since I didn't give her a blue egg, I have no idea when she acquired it.
It is definitely alive, but very dirty.
Pictures from different angles. I put it into the incubator but I don't know whether to turn it, or whether raise the humidity. What do y'all think?

It's probably around day 14-17

I would not raise humidity until I saw a pip.

I probably would still turn it a few more days.

Thank y'all. I was guessing between 14 to 16 days. Appreciate the help.

What's going on with it today?

What's going on with it today?

No change so far. I haven't done more than lift the lid to peak today.

This baby is rockin' and peeping this morning.
Turner is off and humidity is up.
Wish us luck!
