Breeding Questions

[FreyaSuzanne]

So I got two male and two female blue slate heritage turkeys last year. I know nothing about birds but they needed a home and I was willing to learn. Ends up I love these birds. But I also lost both my females to predators. I have a few left of the eggs I hatched but they are related to the toms possibly. Should I just get rid of all the babies and get new girls from somewhere else or is it ok for them to breed together?

I know it's OK with chickens, not sure about turkeys.
@R2elk would know.
