PLEASE someone tell me what this is? It has a broken wing and is at the community College with HER BABY and I need to know if it is a domestic duck or what? I am so worried someone dumped these animals at the pond that has 4 bog turtles that usually get the Mallards babies so I am worried. The baby is swimming by itself. I have not seen these ducks there before and the Canadian geese pick on the Mama duck. Please help me identify it. Any and all suggestions appreciated
