My girl I call Big Mama has been broody going on almost 2 weeks. I cage her so she cannot warm her bum for 3 days as I always have, release her, she seems normal but next day is still broody. I have caged her going on 4X now. Not sure what to do! Tonight when I released her she went directly to the nesting boxes and sat down. She is eating good and acting normal otherwise. Ideas?
