WRY NECK Other Names: Crook Neck, Torticollis, Stargazing, Twisted Neck, Limber Neck Wry neck is not an illness itself but rather a clinical sign used to describe an abnormal head and neck position. Other commonly used slang terms include 'twisted neck', 'stargazing', limber neck', 'crook neck', and 'crooked neck'. The correct scientific term is actually torticollis. Wry neck causes the bird's head and neck to appear twisted and tilted. Depending on the cause, affected birds may initially be unable to hold their head up on their own.
Botulism is a life-threatening disease caused by the toxin produced by the Clostridium botulinum bacteria. Once ingested by the bird, the toxin binds to the nerve endings, which interferes with muscle movements. Chickens will develop paralysis and weakness of the muscles, usually of the neck. They may also have difficulty swallowing, drooping eyelids, and weakness of the tongue. Affected birds may appear lame and only able to stand up and walk a few steps before falling. When the wings are affected, the bird may have both of their wings drooped to their sides. The speed of progression varies, depending on the amount of the toxin ingested and the form of the disease. Usually botulism signs develop within 24 hours to 17 days after exposure to the toxin.
How do chickens get botulism? Botulism spores are widespread in the environment and can be found in dust, soil, untreated water, decaying matter, spoiled feed, and the digestive tracts of animals and fish.
Maggots can also harbor C. botulinum.
