Boneless Chickens, you may well have wondered where the boneless chicken breasts in your local supermarket come from. The answer is from boneless chickens. And we have some life sized rubber models of the birds to prove it. Modeled from life, they are shown plucked and as they might appear hanging in the poultry store window. Seeing is believing, at least in Missouri, so get one and look. This Deluxe Rubber Chicken is 20 inches (50.8 cm) long and made of soft rubber that feels like plucked chicken skin. Hand-painted and bagged with illustrated tag.
