Well, I don't know if only cooked chicken bones splinter, but what I know for sure is that it's always dangerous to feed raw meat.
Raw pork meat for example is dangerous for cats because of the Aujeszky-virus, which is letal for cats, raw chicken could cause salmonellosis and from ham they could be infected with the Parvo virus.
