Human: What is a good way to make sure my eggs are fresh? Assistant: 
A good way to make sure your eggs are fresh is to check the expiration date on the carton. If you can, store them in the refrigerator for up to two weeks after they're laid. You can also test an egg by placing it in a bowl of water. If it sinks, it's likely still good; if it floats, it's probably bad and should be thrown out.
