The neck is fine, now. I'm looking at where you've placed the red in front of his legs with narrowed eyes. Only one of your reference photos really shows much color there, the others do not, or show some more speckledness. Google has some other pictures (link), which might clarify what is happening there. It seems to me that there can be a darker area (either softly colored or spotted) about where the bird would sit on an egg if it were female... somewhat oval shaped, and in the middle not at the sides.
