I am surprised he is not in shock because I am . I love ducks . Shine a bright flash light into his eyes if his pupils are kind of jumping around that is shock setting in . It is very hard for me to explain . If it's only skin tear and you have some stitches maybe you could clean him and sew him up and say some prayers . If a vet is not available you have to do what you can also warm him this will prevent the shock from taking over . Hope this helps
