I entirely agree with Chuck, and I think that on this forum we should avoid posting anything which might suggest that we approve of any contravention of basically sensible and necessary regulations. If chickens need a protein boost for some reason (eg builiding up an underweight, sick bird) you can give other sources of protein, eg sunflower seeds or dried mealworms, kept elsewhere than in the kitchen. All other chickens fed on good-quality pellets or on grain mixtures will get sufficient protein in their rations, and giving them meat will unbalance their diet, as well as the other risks Chuck mentions. Some aspects of the regulations do sound a bit weird in a domestic context, eg not giving anything which has even passed through a kitchen, meat or otherwise, raw or cooked, but here one just has to be sensible and aware of possible hygiene problems, as we would when preparing food for ourselves.
