You are way too early to be asking that question, you won't get any answers other than guesses. I can tell you that there are no White or Black Shoulders but those are patterns. You might compare them in the chick chart that @new 2 pfowl put together.
The female for sure! (spots on the belly)
Males ... the spalding level is so low ... that count for NOTHING!
The spalding level starts to be interesting when you can count the feathers of the neck ( I remind you that on the adult blue peacock you can't count the feathers of the neck ... it's like fur!).
