Ducks have very slippery shit. You really don't want them around your house.
I had a very happy flock of hens laying very good eggs for many years, but when a dog killed the last of my flock I gave up. Very sad.
They were a problem in my vege garden. I never managed to convince them that I was the ultimate authority when deciding when and if something was ready for consumption.
I had a good layer that insisted on going to sleep on my shoulder while I was watching TV, but she was an exception. She was a gift from a Dubby who was leaving town. She is buried under a grapevine.
