If your 15 hatching as Z, place ur 2nd OL over where u plan to place ur hatch, as aposed to sending out scouting. Because buildings being built have a limited sight range, P/T can place buildings around ur hatch without you knowing. With the OL above it, they cannot!

Just adding to that, I found instead of putting your ovie right above your hatchery but to patrol it around the back of the minerals and also just in front to look for cannon/bunker rushes! Can't see behind the minerals if you just leave it above your hatchery methinks!
