So I've got my first very broody hen, she's a pekin banti in her first season of laying and up until recently she has been very good layer. We have had a big chuck go a bit broody but she gets over it pretty quick and only lasts a few days. This one however has been going over month and she's still persisting. If I remove her from the coop she just goes straight back in there, even when there's no eggs. Today I've brought her inside where its cooler and put her in a dog crate so I can keep an eye on her. She's done the usual plucked out her belly feathers, lost weight etc. I want to get her an egg to hatch as we don't have a male and arnt allowed one here but my sister is refusing to do it because she doesn't want babies and for some reason won't sell them. She's been in the crate nearly an hour and is not interested in food apart from a bit of tomato, and she's settled her self down in brood mode pretty quick.

I'm worried she will keep going till she kills herself. I don't like the idea of wire bottomed cage as it could take her a couple of weeks to come out of it and it might cause bumblefoot. I have managed to treat a fairly bad case in a guinea pig with cussioned plasters and sudocrem but I know how problematic it can be.
I read that keeping them uncomfortable can stop them, but she's been sitting in the coop on just wood which isnt comfy at all so she's used to it. Is there anything else I can do to help her?
