Just leave her in there for a few days and nights, then let her out late in day.... if she goes back to nest, put her back in crate for a couple more days.... if she goes to roost, she's broken.
She was still behaving broody, but I just let her out in the yard with the other girls. She's out there flapping her wings and thrilled to be in the yard again! Hopefully, in an hour or so when the girls go to roost in the coop, she'll join them. <fingers crossed>
