Of course you can cut up an off tasting steak and feed it to the birds. Taking care of refrigerator culls is one of the best part of keeping chickens.
If we listened to everything said here on the forums we'd build a large shack to move into so the birds can have range of our houses that we are allowed into to cook them up hot oatmeal three times a day and replenish water dishes with organic cider. Seriously, I've heard some whoppers on this forum from added calcium causes cancer to chickens need cotton sweaters to keep warm in winter....cotton! Nice get wet and cold cotton to wrap around dry down birds. It boggles the mind what some say and do.
