I found this awesome way to tell how fresh an egg is on Pinterest. And I test drove the tip and yup, sure enough it works. You don’t have to draw a smile on your egg though.
A good egg will sink and lay on his side.
An egg that is good to go but not fresh will sink but put his butt in the air.
A bad egg will float.
Thank you Tammilee Tips for the tip and the smile.
