It is said that an egg will stand on its end during the spring (vernal) equinox (about March 21), one of the two times of the year when the sun crosses the equator and day and night are of equal length everywhere. Depending on the shape of the egg, you may be able to stand it on its end other days of the year as well.
From time to time, the Colorado Egg Producers sends out information for educators and the general public. When you register you can select which group to join. You can remove your name from the address list at any time.
