I have seen chickens eat lots of stuff including baby mice/rats, whole shad (garbage fish), stuff picked out of cow patties, small snakes, meat scraps (cooked), each other, (that was kinda gross but a group had eaten most of the tail off a young chicken), all assortments 
 
 
    I like to look at this way.  Maybe your chickens when you were growing up could have fended off the rat or run from the horse if they had excellent responses from eating food not of the bacteria, virus, mold persuasion.  Dogs can die eating compost. 
     I think the chick was attacked because they ate raw meat too.  Once they tasted blood there is no going back.
They are omnivores but if not given the chance they wont do that.  Cannibalism is also caused by using white light over 50 watts around them.  I used 60 but nothing higher and did not have any cannibalism.  The baby chick was no match for a bunch of adults either.  Keep them separated.
Worms, bugs and scrap food from the compost I think is fine but raw meat is not good especially as it spoils and putrifies so is just not healthy.  Our bodies cells are out numbered ten to one by bacteria and so theirs must be high too.  Why stress them out.  They are only going to perform worse.  Just my opinion. 
     Mine were born June 30 2011, and I still get 3 eggs a day when the weather is below freezing but not when it's 10C below freezing.  Then I get two haha.
I have the Stars, three, they call them Bovan's here.  Hybrid from the Netherlands, or a cross of Rhode Island Red and White.
 
 
 
    Enjoy your flock to the fullest
 
I have fourteen inmates, 6 four legged variety and the rest two legged.  They all get along quite well too.
I feed them really good and they are happy.  No reason to fight over food or be territorial and dominant.
We are lucky enough to be by a river so the dogs can run happily too when I get a chance to leave the zoo..
