When can toddler starts eating egg?

My toddler starting to like eat boiled eggs, yeah beside half boiled eggs, he will now peel his own boiled egg to eat. 

The fun part for him is cracking the egg, first we were scare to let him to handle the egg. We need to be there to watch him eat, ask him to chew every time he bites the egg. 

This Friday, my toddler is turning 3 years old. 

We always watched him eat and sometimes he's playing with his food. He dislike eating the egg yolk, he will remove it. 

I remembered his bro during childhood, he's was 3 years old back then during his birthday. He would be cracking up all the red eggs to find dinosaur inside. He would be crying to find there's no dinosaur toy in the egg. 

You know there was time some places selling dinosaur eggs, which contain a dinosaur toy inside. It's not the same egg but to him it is.
