David Sibley has an essay on distinguishing Common Moorhen from Common Gallinule here.
The "Birds of North America" account for Common Gallinule mentions, "Chick has a 1- to 1.5-mm-long spur on alula (wing) that permits grasping when chick climbs emergent vegetation, enters nest, or clings to submerged vegetation when swimming underwater (Bent 1926, Miller 1946, Wood 1974, Greij 1994)." This may be what appeared to be an external wing-claw in one photo.
