My experience goes about like this: After her setting for 3 days and nights in the nest (or as soon as I know they are broody), I put her in a wire dog crate (24"L x 18"W x 21"H) with smaller wire(1x2) on the bottom but no bedding, set up on a couple of 4x4's right in the coop or run with feed and water.

After 48 hours I let her out of crate very near roosting time(30-60 mins) if she goes to roost great, if she goes to nest put her back in crate for another 48 hours.

Tho not necessary a chunk of 2x4 for a 'roost' was added to crate floor, gives the feet a break from the wire floor and encourages roosting.
