Some chickens just are very clean that way. The white Ameraucana on "my page" did not poop in the dog bed. She slept with the dog. They were best buds. I have a chicken in the house right now that doesn't poop in her bed. Chickens make wonderful house pets. They are very social and love to be where ever you are. Yes, you can have just one chicken, if it is in the house. Most of my chickens usually live outside though. Oh and I do use chicken diapers sometimes.
