Stopping broodiness - advice please

Hope someone's got some advice that isn't too extreme. I've got a Sussex Reverse who's been broody now for about 6 weeks. We remove her from the nest box every evening when we get home to make sure she gets food and water and started closing the door to the coop to stop her going back in too quickly, but she's being stubborn about it. Is there anything we can try to get her to stop being broody? She seems to be breaking her egg recently (not eating them thankfully) which is an additional worry. I don't want her twigging that it's an easy meal. I've read some very odd bits of advise such as swinging chickens around, locking them in the dark with no food for a couple of days etc, but frankly I'm not keen on these options!

As above, I need to do it to one of mine aswell, been like this for about 2 weeks now

Stablechooks description  exactly fits our experience. I used a washing basket as the top of a cage with wire bottom. Always left food and water. Placed contraption close to coop under shelter and safe within fences. Six weeks to three days - a miracle. Nothing else had worked and even though she's in a small space, she wasn't moving from the nestbox, so I don't think there was any cruelty.

If you have a handy family member you can quite easily make an anti broody coop. My OH made one out of ply sheets and some left over 2'x2' timber with a lift up lid made out of laminate flooring strips and a mesh bottom to allow air circulation. We have a piece of MDF that we can drop into to cover the mesh base and slots to drop in a roosting bar, so it doubles as a segregation coop if we need it too. I posted a photo somewhere but can't find it now.

HERE is your post Jomtie.
