New Duck syndrome is most common in ducks but is also found in wild fowl, and turkeys as well as game birds. This disease is transmitted by bird to bird contact such as a toe nail scratching another bird, especially in young birds. This can also be spread if the birds have a respiratory infection or cough, with liquid coming up in the cough. This is also spread through feces contact with food, water or even through litter, because of harboring bacteria, and pathogens.
