We have a handyman who became a close friend over the years. Often, he refuses $ for his services, so I slip him some eggs instead. He built our coop, so it's only fair that he gets some eggs from time to time.
Likewise our next door neighbor is like a second grandma to our kids. She won't take money for babysitting or pet sitting while we're away, so we pay her in eggs & garden veggies.
I'm a science teacher & use raw eggs for some of our labs. (Egg Drop, Egg-nertia, Egg dissection, etc.) If the student's design works, the egg remains safe, &/or the assignment meets the requirements, the prize is the egg. The kids loved knowing which chicken made their egg & the parents were impressed by their children's strong motivation.
