for hard boiled eggs, boil each egg 8 minutes
If you put then all into the same pan and boil them at the same time, then the answer is the same time as it takes to boil one egg. A hens egg for example would take 3 minutes to soft boil and 8 minutes to hard boil.
6 minutes
I always boil eggs for at least 20 minutes just to be safe.
No matter how many I boil, I put them in a pot big enough that they don't stack. Cover them with COLD water. Bring the pot to a boilo and let it boil for 8 minutes. Remove from heat, cover and let set for 10 minutes more. They should be perfect.
8-9 days
i have heard about 8 weeks.
It depends upon the size of the pan you are using, and also whether you want them soft or hard boiled. A large saucepan should be able to accomodate 6 eggs- assuming you want them hard-boiled, this will take about 8 minutes from first putting them in the boiling water. There are eight lots of 6 in four dozen, so to find the time it takes to boil four dozen, multiply 8 minutes by eight, which makes 64 minutes - or 1 hr and 4 minutes.
Four days.
1 kilowatt = 1000 joules per second, so it will take 480 seconds. (8 minutes).
The best way I have found to cook hard-boiled eggs is to put your eggs in a pot with enough cold water to about 1" above them, turn on high, wait for it to boil, boil two minutes, take the pot off the heat, put a lid on the pot and let sit for 20 minutes, rinse with cold water. They usually turn out perfect.
about 28 days or 15 million years if its a golden one 8-)
