Having fed my dogs raw chicken on the advice of my vet, I have to disagree. 
It is only if the chicken (avian) bones are cooked that they are a problem. 
Of course, most of the bird bones found in archaeological sites were 
probably cooked unless they are found in a midden. (wings, legs, etc that 
are not utilized for food)
