How much for eggs?

How long does it take to boil an egg? (i can never get it right)

I am 18 and i'll be 19 in next month.it has already been a month since I joined gym.I'm eating 10eggs per day as it is protein booster food as told by our gym trainer.among 10 eggs I only eat 5yolks.I want to know if it is okay for me or not?should I have WHEYY(protein powder) n lessen number of...

I buy my eggs from a local farmer. But the white is runnier than the ones I buy at the store and the yolks are pale yellow almost white. Does that mean he's storing them or that he's feeding them something different.

I am trying to get my scrambled eggs more fluffy and well done at the same time, however they always come out dry and flat can you help me.

This might sound stupid,but does anyone know how long it takes to boil a perfect egg? Thanks.
