The coloring is not lavender, it is blue. The picture of her being held falsely makes her look more "petite" than when she is naturally standing, so I'm assuming that's why they guessed that way. Is her skin color pink? It appears to be in pictures. Check foot bottoms to be sure. If so, likely a Blue Orpington. Blue Rocks while being a hybrid, should retain the yellow skin color from what I have read.
