What's the matter with a crooked chicken neck for eleven days?

Chickens with crooked necks are mostly caused by neurological symptoms. Such a small chicken may be vertically transmitted salmonella. Pay attention to observe whether there is white dysentery in large groups. If there are white spots in the liver of dead chickens after dissection, it is recommended to treat them with drugs for salmonella. Chickens with crooked necks can be eliminated directly and have no feeding value.
