#1. True and False... Ducks clean themselves, so naturally (in nature) they would be flying to ponds and cleaning themselves on a daily basis. In captivity, the owner of the duck would have to provide the means of cleanliness (a small pond or a little kiddie pool). Without the husbandry of the person keeping the ducks, they would not be necessarily healthier. Chickens on the other hand, clean themselves using a dust bath. If your chickens are free range, no work is required for him/her to know that the chickens are staying clean (the chickens will do that work by themselves). If the chickens are in a pin, the owner would just simply have to provide a pan with sand in it. When having to provide cleanliness to ducks and chickens, the big difference is that ducks will destroy their source of cleanliness (you will constantly be changing the water / cleaning the source / because ducks defecate in it), and chickens will guard their source of cleanliness (they will keep their dust bath area clean). Winner in this question - Chickens....
