Breaking broodiness

[Snicketysnoksnaksnik]

Hello, I’m in desperate need to break my chicken out of being broody.
She’s been broody on nothing for around 3 months and she’s gotten quite skinny and I’m really worried.
If I take away her nest she just sit on a table. I’ve been trying to break her out of being broody by using the soak method but I’ve gotten no progress

She’s a bantam, not sure what type though.

Update: going to put her in a cage with food and water during the day and in a mesh-bottomed cage with a roost at night
