Funny you have a garden. I started one after we got the chickens so they can have fun in the raised beds scratching and bathing when it goes fallow for the winter. Now we've got two raised beds and a bag bed to raise veggies for them and ourselves pesticide free and as organic and heritage as we can. As for duckies - they're easy to please re: water - a baby pool for a couple of ducks will make them very happy - there are some docile breeds to choose from to keep around chickens. Pekins are a great tame breed and they aren't bad layers but like with every breed there's a downside - they're chatty. Of course if you're on water rationing like CA it may be moot.
