Oh, sorry. Actually, I still have something to ask about your answer so I have not click the check yet.
No.2: 'No'. Do you mean I can get shiny by just having two normal parents? or do you just mean "no,the shiny won't be hatched like that".
No.4: if it's all no, then what is the different between shiny hunting by chaining and 1/8192 chance?(not telling about the using poke radar or not) I think I can encounter different kinds of pokemon. Isn't those lucky people get their shiny pokemons like that? You don't need to encounter the same pokemon in a row for 1/8192 chance hunt. And, didn't they sometimes "run away"?
I'm confused now.
