My girls get to stay their entire lives. Nobody gets the axe because they have stopped laying. Heck, a chicken gives you about as much affection as a dog (mine do anyway) plus eggs for years, and I wouldn't think of culling my dog because she didn't give me enough in some way. That's just my take on it, but others have a different viewpoint, I know. But then, many havent experienced a chicken tugging on your pants leg to be picked up and cuddled. If they did, it'd be pretty hard to put its head on a block.
