Throw away into the dumpster?
give it back to Easter Bunny?
I'll share my secret...
Real eggs contain minerals such as calcium, iron, magnesium, phosphorus, potassium, sodium, and zinc.
So, I gave it a good burial.
Step 1: The Site
I chose a good burial site, e.g. next to a tree.
I dig a hole near the base of the tree. The depth of the hole is at least 6 inches, and the width is enough to fit am egg. Then, I put the egg a the base of the hole, and cover up with earth.
The egg will rot away in the ground, and acts as a organic fertilizer for the plant (e.g. calcium, iron, magnesium, phosphorus, potassium, sodium, zinc etc)
Step 2: The Other Site
I also buried the egg in a planting pot, or...
Step 3: The Grand Burial
If I have a batch of eggs, I buried a few in a large pot, and plant some tree in it.
It has solved my problem. You should give it a try too.
