A chicken is not going to eat a scrambled egg then suddenly look in the nest box and think the egg in there is the same thing! Giving them a raw shelled egg would be a bad idea...plus its messy! Ever see an egg eaters face? lol
I do feed any cracked or dirty egg back to the chickens, after cooking it. What else am I going to do with it? Especially in this weather when eggs are freezing before I can collect them...and they need the protein. Then again, if I stew one of my boys and there's some left over I feed it that to the chickens too. What they don't know can't hurt em
As far as cannibalism, it's surprisingly common in the animal kingdom. Maybe not so much among birds, but rodents, sharks, alligators, spiders, certain chimps, crickets....lions have all been known to kill and/or eat their own kind. Though it is more common for them to kill and eat their young. Ewwwww!
