As MJ points out below, there are always outliers. I found getting them to roost on a bar overnight did often do the trick. It makes sense because their chest and belly area they would keep warm while sitting is exposed to air movement which is essentially how the broody breaker cage works.Not my Snowy.![]()
As always, the keeping circumstances have an impact. If the hen can return to her nest, or find another nest she can sit in things get more complicated.
I've had broody hens intent on sitting attempt to sit on eggs laid by other hens in another tribes coop. That was interesting.
