BAKE SALE!!! Your local church, flea market etc. Make some nice cookies or whtever and take a few dozen extra eggs. I like to keep a pile of copies of an article about how healthy free range eggs are compared to store bought next to where we sell the eggs.
Or if you don't want the hens to help pay for their feed, you can donate them to a local school, shelter, or orpahnage, etc.
