Hard boiled eggs of covey

Today, I challenged to make a hard-boiled egg of covey.

Preparation : eggs of covey, one onion, 1 cup of water, 1 cup of soy bean,
some powder of sesame
Recipe : 1) boil eggs of covey for 15 minutes
2) peel eggs of covey
3) put peed eggs of covey into a small pot
4) boil them for 7 minutes
in mean time, arriving at about 5 minutes, put some slices of onions
5) sprinkle some poweder of sesame

It seems very easy to boil eggs of covey. However, as eggs are so small, and if eggs are too much boiled, shape of eggs are not well formed while peeling.
This time, my mother helped me, however, next time, I can do it by myself.
