Hens go broody when you don’t want them to… and won’t go broody when you do. 
Heartbroken. I put my sweet Sassy down today after only two years of life. I suspect she suffered from oviduct impaction, and everything I read about this condition, and all of her symptoms led me to the realization that she could not recover and life had become a struggle. She’s on the other side of the bridge now, scratching in the grass and chasing bugs and lizards.
