This can work with some birds to break broodiness. I have done it before. I give them about 3 days then I put them back in. Sometime they need longer so continue to monitor her behavior. Good luck and welcome.Being new to raising chickens as pets, I acquired 2 white silkies a couple of months ago. I recently observed on of them staying in the nest box. She was laying eggs pretty good, but there are no eggs under her, plus she is not laying eggs. I did some research and found out she is Brooding, not what I wanted her to do yet. BTW I have a small rooster, not sure of the type, it does have feathers on its legs though. I am presently to break the brooding thing by using a dog cage as a deterrent so she will stop. If my picture goes threw showing her in cage, Am I doing the right thing
