... With a creature such as poultry, castration is inhumane....
So it is inhumane (according to some) to kill and eat a rooster but I personally feel that it is more inhumane to eat a rooster without first killing him. Then it is inhumane to raise purpose bred chickens that in most respects are the same as a Capon or a castrated rooster. What you seem to think or say is that anytime a human lays his or her hands on a chicken it is basically a cruel or inhumane act. The chickens in a fryer-broiler house are basically a Capon without the operation.
