I'm glad you are bringing this up here, it seems to have worked well for some people. Why not give it a try?
The theory is that the egg starts giving of fumes or gases that aid in the rooting process.
I believe it went like this: take a pot, put in about 2 inches of a well draining mix, put in the egg (in its entirety, shell and all) and add another inch of soil on top, then put in the stick, and fill the pot. Stake well. Keep warm and apparently there are people that have done comparisons and it has really sped up the rooting process.
Don't we all have some eggs lying around that we don't want to eat ?
