What is the lifespan of call ducks fed only on Mazuri feed? And kept in a clean and sanitary environment free of pests and predators?

I'm not sure anyone's done a study on this and collected the data. Generally speaking, a good diet, good genetics, good environment and no predators is gonna have a good lifespan
