Expired eggs...what to do with em?

Make sure they are actually bad first. Place them in a container of water...if they sink they are good and if they float they're bad.
Hard boil the good ones and crack/compost the baddies.

Use them as fertilization in your garden

Throw them at an enemy's door?

Eggs can last weeks or even months after the expiration date, altho the quality won't be as good. Use them if they are just past expiration. If you are worried, break each one into a separate bowl before adding it to what you are making. If an egg is bad, you will know it!!

Put each one in a glass of cool water, if it floats throw it out, and if it doesn't it's still good.

Expired I would toss them out in the trash, one day before expiration, I boil them all.

Compost
