Each image has only what the wording above the image says. The first image is of chicks from Rose Comb Leghorn hens crossed with a Cream Legbar rooster. The second image is of Sapphires which are an F1 hybrid created by crossing White Leghorn hens with a Cream Legbar rooster. The third image are from Sapphire hens crossed with a Cream Legbar rooster.
It is very common for many of the Sapphires to have some random black spots. The Sapphires are not auto sexing. The Sapphire/Legbar cross did produce some but not all auto sexing chicks.
The Rose Comb Leghorn/Legbar crosses were not auto sexing but when they were crossed back with the Cream Legbar the next generation were all auto sexing.
