Using a turkey for chicken egg hatching

[Japetus]

Among all the chicken I have one 1yo female turkey.
The previous two weeks she used to disappear in the mornings and return to the rest of the flock at noon. Initial attempts to locate her were unsuccessful. Two days ago it was raining and she didn't return for the night but next day she did. Finally I've found her nest hidden under a bush with 13 eggs, her first ones she ever layed. I removed them and replaced them with a dozen fertile chicken eggs. She sat on them but the night she left them to return to the coop.
Today, I found out that she had layed one more of her eggs among the rest and the evening remained at her nest.
Questions as I know nothing of turkeys hatching eggs.
Is her behavior normal? Returning to the coop at night until she feels that she layed enough eggs? As it's her first time is there a risk to stop the hatching?
How many eggs do they usually lay and with how many chicken eggs can I safely replace them?
Can I move her and her eggs to a safer and more protected place or I should not disturb her now?
Can I add 3-4 more eggs tomorrow or will she stop hatching them once the first chicks are born?
As I have only experience with chicken hens so far, is there something I should be aware of when the eggs hatch? Should I leave the chicks with the turkey or remove them from her?
Thanks and sorry for the many questions..

First time laying turkeys can be an iffy thing. Some will go broody and stay on the nest, some will seem to go broody but will leave the nest at inconvenient times such as a night the temperatures drop below freezing.

Turkeys can be hard on chicken eggs but some people have used a turkey hen to hatch chicken eggs.

Each turkey has its own requirement as to how many eggs are needed to set off her broody alarm. The amount can greatly decrease late in the season. Normal required number of eggs can be anywhere from 8 to 12. I have had hens that did not go broody until after there were in excess of 20 eggs in the nest.

You can try to move her and her eggs but there are no guarantees that she will accept the new nest. The best chance of success is by moving the nest into a small pen that makes it possible to pen the hen in with the new nest. The farther along the hen is in her broodiness, the more likely she is going to accept the new nest.

R2elk, how right you were.. The turkey hen left her eggs twice in the first nights but I decided to let her continue hatching.. She even layed a couple of eggs more. A week ago she started laying again, and did lengthy pauses for feeding. And then suddenly as I went yesterday to pick up her newly laid egg, I saw three chicks having hatched, and three peeping eggs semi-open.
I removed the three chicks and placed them in a brooder but unfortunately today the rest of the hatching chicks in the eggs were dead.
Should I remove the rest of the unhatched eggs and force the hen to abandon the nest or should I wait a few days more to leave them on her own?

You can do either. Birds can get away with things during hatching that if we tried to replicate the situation, we would fail miserably.
