Muscovey ducks are great bug eaters. They do not need a pond to swim in (a water bucket or a kiddy pool good for them) They don't quack, the drakes hiss and huff and the hens kinda squeak. They are wonderful pets and easy keepers. They do fly and may need to have their wings clipped. They are not destructive.

Chickens are great bug eaters to but are notorious garden and flower bed dimolishers.

Guinea Fowl are a love 'em or hate 'em bird. I love them. They are another great bug eaters (and snake eaters) They can be/are a loud bird that sound an alarm when any strange person or animal sets foot on the property. They are not known to dig like a chicken and wreck your gardens.

Geese are great grazers and will clean up all the grasshoppers and crickets, but do not do much to keep the fly and 'skeeter poopulation down.

I have no experience with turkeys yet.

Both the Guineas and chickens will eat mice (mine do anyway) small snakes, frogs and sometimes baby birds that fall outta the nest.
