Which characteristic is associated with a market bird that has a non-protruding broken bone?

A market bird with a non-protruding broken bone is typically characterized by a bright red comb and wattles. This feature indicates that the bird is healthy and in good condition despite the injury. The comb and wattles are key indicators of a bird's vitality and overall well-being. When these features are bright and red, they signal good blood circulation and that the bird is likely receiving adequate nutrition, which is essential for recovery and maintaining market standards.

Other characteristics, like weak muscle tone or visible feather loss, would generally indicate health issues or neglect. Enhanced feather quality would imply the bird is in pristine condition without injuries affecting its appearance. A non-protruding bone suggests that while there is an injury, the bird's general condition remains good enough to exhibit strong coloration in the comb and wattles. Thus, the correct answer underscores the connection between health indicators and animal vigor, even in the presence of injuries.
