Congratulations. So pleased it has gone well and she has accepted them back.
It is likely that she will go broody next year but not guaranteed. You may also find that she favours late summer again rather than spring. You may also find that if she has any biological daughters they might inherit the broody trait.
I have a bantam silkie/cochin cross and she is a good broody but my favourite one (Tasha) is a supposed araucana that I bought at auction for a fiver because no one would bid on her. She's actually a scruffy little mutt although there is some araucana blood in there I think. The great thing about her is that she lays eggs all winter when the others knock off and then raises chicks in the summer when the others are producing plenty of eggs. If I knew how she was bred I'd have half a flock of them. Her first brood, she set and hatched 14/14 of her own eggs and safely chaperoned them all till they were 7 weeks and that was free ranging amongst a multitude of hazards! And she had to put up with me fussing and interfering which in itself qualifies her for a gold star (it was my first experience of a broody and I faffed a lot!!)
One of my new broodies which is currently raising chicks, is one of her daughters from that first clutch.
I hope it continues to go smoothly with your broody and chicks and you get as much pleasure from watching them as I have mine.
