One of my chickens has been broody for the past 30 days. She had eggs under her for 29 days but none of them hatched. We took the eggs out and she is still broody and laying on nothing i thought she would stop when i took the eggs out but she didnt...i tried the ice cube trick and it didnt work, she just laid on the ice cubes. I have no idea when she will quit and what other ways can i get her to stop?
