I went to the feed store and bought 4 chicks for her - only being particular about them being as young as possible. I ended up with two buff orpingtons and two javas and I settled them under her at night. At first she seemed surprised and somewhat confused. Then she started cooing to them and fluffed out her wings and got comfy with her new chicks. And the babies took to her like she was their mom the whole time.
In the ensuing days she has been very protective over her little brood and they are thriving under her care.
I adore how they hop in and out of her feathers like popcorn. Here I caught a chick making a dive for safety.
And here is one that loves nothing better than peeking out at the world from her mom's wing.
