How can you tell if a 1 week old wild baby robin is sick?

To determine if a one-week-old wild baby robin is sick, observe its behavior and appearance. Signs of illness may include lethargy, lack of appetite, unusual vocalizations, or difficulty in maintaining balance. Additionally, check for physical symptoms such as abnormal droppings, discharge from the eyes or nose, or any visible injuries. If the bird appears unresponsive or weak, it may require assistance.
