Create small hole in three eggs. I just made a small crack, poured out the egg inside and broke off small pieces until your holes are the size you want.
Use Easter egg dye to color the egg shells blue.
Attach a base so that your eggs will stand upright. I use these glass vase fillers.
Fill halfway with Easter grass.
Place chick inside.
Now you can display them however you like. I found this cute plastic egg for $1, added a little more grass and set the blue eggs inside.
Notes
While I've included links to help you find these products on Amazon, you can find them cheaper by going straight to Walmart or one of the dollar stores.
