Laws on keeping ducks

[Cali Hi]

lol! Thank you all. They are Muscovy ducks. There are no CC&R's on the property, so it would be an island rule/law, and I couldn't find any. The ducks do occasionally go into the neighbors yard (I assume they go there because she has good bugs for them to eat) I think she's just too fussy for her own good.
Wildlife, the wonderful food you can grow on your land and keeping some livestock was one of the things that drew us to the island in the first place.
Eating the slugs is reason enough for me to keep ducks!
