I'm getting some new chickens soon and one of the breeds I'm considering is a silver-laced Wyandotte, which is prone to broodiness. My question is: if a chicken goes broody, does she ever become productive again? If so, how long does the brooding period last? Also, I have a small backyard and I would not be able to accommodate any extra chickens, so I would not be able to indulge her broody behavior- would this be harmful to the chicken?
