A distressing video of chicken supposedly infected with Newcastle disease left poultry farmers with many unanswered questions about the disease.
In the video widely shared among farmers on social media, dozens of chicken feeding in a dimly lit room suddenly start arching their heads backwards as they uncontrollably move back and forth. Others hysterically throw themselves on the ground and writhe for a while, trying desperately to tuck their restless heads in their wings before they fall silent.
