Prevention and Control Methods and Technical Key Points for False Layers

Prevention and control of false layers: First, for chicks that contract infectious bronchitis during the brooding period, especially before 2 weeks of age, the entire flock should be culled if the condition is severe; individuals affected at an older age or with milder symptoms should be treated promptly and management strengthened. Second, when false layers are confirmed in a flock during the laying period, they should be identified and culled as early as possible. The method for identifying them is to perform a rectal examination on each bird individually or to keep laying records.
