Question of the Day
Many hens in a large backyard flock recently became ill after the owner purchased four new chickens. The sick hens are gasping, coughing, and sneezing.
They have poor appetite and act depressed. Some affected birds have watery green diarrhea and swelling of the head and neck.
A few have paralyzed legs and wings, twisted necks, are circling, and have tremors or clonic spasms.
Birds are not laying well and some eggs are misshapen with watery albumen. Many of the sickest birds have died.
Necropsy of a dead chicken shows petechial hemorrhages on the mucosal surface of the proventriculus and gizzard (left).
What should be done next to address this problem?
