Animals dont belong in the house.I grew up on a farm and chickens are a nasty creature.[unless they are southern fried in flour and buttermilk]!
We spent a few months in China, and you can't believe the unsanitary conditions in the marketplaces (where most Chinese go to get their food.)
Chickens, dogs, cats, rats, snakes, (you name it, they eat it)...all being held in cages, waiting to be slaughtered and then their "guts" just get washed into the street and down into the sewage system.
Smelly and messy...I was paranoid about us cleaning our hands after we touched put on or took off our shoes, LOL.
True enough.But try to convince the 2 billion people in Africa and Asia (and maybe other places) that disagree with you.
