Yup. it's often difficult to know what to do for the best.The fathers is the rooster of her flock, and she did live with the other hens.
I would have liked to leave her to bring the chicks back by herself, but I was getting to worried about foxes, snakes and birds of prey, so I put the her and the chicks in a cat crate and put them in the coop last night.
I don't know if this was the best thing to do, but she seem ok with and I think it will work out
If I could find the outside broody I moved them and their eggs to a spare coop.
When they sat and hatched in my house I either moved them all to a maternity unit outside my front door on day 18 and crossed my fingers.
Those that sat and hatched in their tribes coop obviously had an advantage in integrating into the tribe.
Those that hatched in my house I moved as soon as mum had finished sitting.
I think what you've done should be fine.
