Answer 1

Almost no. It is VERY hard to get a Shiny Pokemon besides the Red Gyarados. (Learned from experience, and the internet) Chances are unchanged, 1/8192 I believe, tell me otherwise and I will edit. I actually have a few. So Basically most unlikely. 1/2048 Masuda method (In only Gen 4? Really? Didn't know that)

Wrong. 1/8192 isn't just the chance.

Ah, yes, the Masuda method. Forgot about that one :b....

Oh, and saying that someone else is basically right will most likely get you down-voted. Learned that from Josh and Experience.

If I didn't say "Like Ninja said," I was afraid I might be plagiarizing.

Answer 2

Possibly. You have a 1/8192 chance of it unless you use the Masuda Method, which takes the chance to 1/2048 in Gen4.

Basically: Most Likely not.

Answer 3

No, Breeding a shinny Pokemon will not always lead to a shinny Pokemon, though it is possible to get a shinny Pokemon from breeding it is very very unlikely
