The most common form of scoliosis is idiopathic scoliosis. Unfortunately, in this case, there is no obvious cause. The condition may be inherited, but that theory is still being tested.
Step 1: The Boiling Stage. Put up a pot of water to boil â you'll need one big enough for water to flow freely around the number of eggs you'll be cooking. Once the water's boiling, use a large spoon to gently lower the eggs into the water. Lower the heat to maintain a simmer and set a timer for 12 minutes. Now, don't stress...if you let the water boil a little too much or drop below a simmer or fish out your eggs 14 minutes later, it's okay.
1 boiling: For a slightly runny yolk, boil an average sized duck egg for 6-7 mins. 2  If you want a hard-boiled egg, cook for 9 mins. 3  The shells are more fragile than hen eggs; to help avoid them cracking keep them at room temperature and lower them gently into the water with a slotted spoon.
