I would be concerned about that for industrial chicken crammed into a building. In these cases they medicate the feed so less die and in some cases have to scoop the dead out with a tractor. 

 I imagine a chicken raised on pasture and moved often would not have too much of either of those 

 I think they would have as well  

 cats are obligate carnivores 

 I know.

But honest question:

Why not cook the meat?
