From The Pagan Family by Ceisiwr Serith

During the day, boil thirteen eggs as a family. If there are a large number of people in your family, boil twenty-five. Dye all but one of them Sun colors (red, yellow, and orange). This can be done the previous day if time is a problem. Leave one white. At dinner, put them in a bowl next to the sun candle in the middle of your table. Put the white egg on the top of the pile. What you will have is a bowl of one or two suns for each month of the year, plus one winter egg.

After sacred time is established, an adult picks up the white egg and bangs it on the table to crack it, and removes the shell, saying:

The ice cracks
He removes the white, saying:
The snow melts
He holds up the yolk, saying:
The Sun is coming back.
And now that he is armed
and now that he is strong
He will chase away the cold,
he will bring us spring
and summer is sure to follow.

Pass around the pieces of the egg for everyone to share before starting the rest of the meal. Eat the colored eggs with the meal. If desired, one can be reserved for an offering.

An Easter tradition practiced in many places that is good here (especially if your version of the Wheel of the Year puts the beginning of the battle between winter and spring at the spring equinox) is egg fights. Each person chooses an egg. Two people then face the small ends of their eggs towards each other. One of them hits the other's egg with his own. When one person's cracks, he turns his around and has another chance with the other side. When both ends of an egg are cracked, that person is out. The game continues until one egg is triumphant.

Another game that is fun to play is balancing eggs. There is a belief that the only day that a hard-boiled egg can be balanced on end is the equinox. (Not true, unfortunately; it can be done any time, although it is always hard.) The idea would seem to be that on the day of balance between night and day other things can be balanced too. Since you'll have a whole bowl of them in front of you it would be hard to keep from giving it a try.

Save the colored shells until May Day.
