We used to make our cages from some welded wire fencing and some sticks. It doesn't have to be elaborate. We had about 5 cages hanging from the roof of the henhouse. Frequently there were a couple hens in broody jail.
I now use a wire elevated dog crate. I leave it in the coop for the bird's security. If caught early, it usually only takes about 2 days. After 5 weeks of broodiness, it could work quickly or it may take a long time, depending on the hormone cycle.
