OK, I guess I will be the first.. NO I do not feed chicken to chicken.
I think Soylent Green!!
We human omnivorous are very capable of eating our own kind too... Our society does not because?? We have other options for food?
Yes Chickens are always hungry and will eat anything. I am sure if I fell and bumped my head and was bleeding while I was passed out the chickens would eat me. We do live in a eat or be eaten world.
It is my opinion that in a natural environment chickens would rarely if ever have a chance to eat one another. Most likely a larger predator would eat the weak or injured. Since we keep chickens confined, it is our responsibility to provide the "options" they have in their diet.
I will feed mine fish or small amounts of other than chicken meats..
Know if I were raising fish, I would have no problems feeding fish to fish, since that is all they eat in nature as carnivores.
Just my take on it..
