May be a type of deformity that is cause by a silent disease.
A fellow at our church raises cows. O.K. Well one of his cows gave birth. Well the calf has 1/2 a nose. So that tells the owner that somewhere down the line something bad happened. 
He can't sell the calf for meat or anything. He can have it killed but, why? He says he will let it live out its days, but he also said he wouldn't eat it, cause he knows something just isn't right.
That's why it was said that something is wrong. Not saying it is an unhealthy bird but, just saying, if the bird doesn't have a neck, there's gotta be something wrong.
