Can chicks hatched in incubator several days after hen hatched eggs be raised together?

So hen went broody and stole 18 eggs to sit on. After 3 weeks, 2 hatched quickly and naturally, one additional did not survive. At that point Mama abandoned the nest for a few hours and…went for margaritas and sushi I guess. We moved the other eggs into an incubator, and are learning as we go.

Mama returned and is taking care of her two little Roos, and is not rejecting ( but not particularly attentive to) the little girl that fought for almost 36 hours to hatch in the incubator. Now two days later, another little girl has hatched, and another egg is rolling around. Is it safe to place these new chicks with Mama?

Details: Mama and chicks are in an Eglu tractor inside a large chicken enclosure, so chicks are safe from the rest of the flock. They are Bielefelders
