I haven't had chickens in a very long time, just my ducks these past few years and a couple of Toulouse ganders for a while. On the whole, I don't find the ducks that noisy. Certainly not like a crowing rooster! The drakes are very quiet as only the girls actually quack. There is usually one that is loudest and complains all the time. But, not THAT loud. Also, my Saxonies are quieter than my Welsh Harlequins. I don't find them much trouble to take care of. Just clean up the duck house every morning, put out feed, put clean water in their waterer and change the water in their kiddie pools. Takes about a half hour. They tend to poop around the pools, so I wash that down every day. They will find any little puddle of water and do their best to dig to China - just fill it back up with dirt. I don't know why people think they are so messy, as it's not like chickens use little chicken toilets!
They will eat grass and seeds and bugs and snails and lizards and small frogs and small snakes and mice and leftovers. Best thing for cleaning out the fridge except for pigs!
Get some - you will love them, I promise.
