Eye, healthy chicken
Eye, healthy chicken

    Eye of a healthy chicken with no discharge or inflammation. Note the pupils are round and symmetrical, and the iris is a reddish-orange, copper color.

    For an examination, observe the eyes, and check for any discharge or cloudiness that may indicate illness. The eyes of a healthy adult bird should be clear and bright and have a copper-red iris and a round pupil with well-defined margins. Young chicks generally have a blue-gray iris. The eyelids should be free of swelling and opened wide.
