Donald is a pet outside duck. he is 13 yrs. old. Eats fine poops fine swims in pool fine does all his normal activity. notice his feathers seem to not repel water like they should and he seems wet afterwards. he has lost a little weight. Is it his age or a problem do you think. What is the life span of a spoiled outside city duck? It's a drake. He has a friend and the 2 drakes get along fine. Other ducks feathers are good.
