The egg can't work because there's no real way to determine the SID from it since you don't know the PID. When breeding, the PID and IVs aren't combined together, so there's no way to know the exact spread you got it with.

Chain can work, but as the chain gets higher up, the game makes more calls to the RNG to get a shiny, so it sometimes gives one that normally wouldn't be.

Red Gyarados won't work because it's set shiny, so that's not an actually shiny spread you have.
