I have various labels I put on my egg cartons. One says "Parker Perfect Eggs" " The Best Because We Give A Cluck" With a cute chic pic. People seem to be amused by it.
I'm working on signage for the front of the coop that says "No one in here but us Chickens" and my next door neighbor handmade a clay sign for me this summer that says "Poultry Seeds - Lay or Bust."
