Thank you so much for the clarification! I just got some legbar (assuming it's a cream) over a leghorn (not sure on the comb) she had no idea why they look the way they do. I was surprised myself not knowing anything. Just that sexlinks tend to have the dot on their head. Here is a picture of them. Some very wide barring. Almost looks like stripes.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.
