We advise isolation of broodies from the moment they appear (in the evening). Place them in a spacious pen, on a concrete or slatted floor without a nest. Treatment is made more effective by dipping the broodies in cold water for 20 to 30 seconds and administering aspirin (a 125 mg tablet) before transfer to the broody pen. The density in the pen must not be greater than 6 per m². The birds must have feed and water permanently. At the end of 4 days, those which respond (widening of pelvic bones) can be placed back with the flock.
