Chop the chicken and potatoes into 1/2-inch cubes and add them to a large bowl. Chop 5 1/2 of the eggs into 1/2-inch cubes and add them to the bowl, reserving half an egg for garnish. To this, add the shredded pickles and green peas (reserve some for garnish), and season with the salt and pepper. Finally, add in the mayonnaise and dill and mix everything together carefully.
Shape the mixture into a rounded mound and cover it with a thin layer of mayonnaise. Decorate the mound with green peas, sliced pickles and the remaining half hard-boiled egg on top, cut into the shape of a flower (optional).
