Our chickens get every table scrap that isn't toxic to them. Instead of scraping our plates into the trash can, we open the sliding back door, then scrape the plates off the edge of the deck. If we're really lazy, or it's raining, we just throw stuff from just inside the door into the backyard. Our chickens, ducks, and turkeys all free range, and I have to say this system has created some treat monsters. Whenever they hear the door slide open, they come running from all directions. It's quite a sight. If they don't feel like they're getting treats often enough, the turkeys will climb up the deck stairs and knock on the glass door until someone acknowledges them. (And yes, I made the mistake of rewarding that behavior with, you guessed it, a treat. My husband says it's only a matter of time before they break the glass and help themselves to the refrigerator).
