Reduce heat to medium-low; simmer until sauce thickens and is reduced to generous 5 cups, about 1 hour. Season sauce to taste with salt and pepper. DO AHEAD Sauce can be made 1 day ahead. Cool slightly. Chill uncovered until cold, then cover and keep refrigerated. Rewarm sauce before using.

chicken
Place chicken breast halves between 2 sheets of plastic wrap. Using meat mallet or rolling pin, pound chicken breasts to 1/3-inch thickness. Sprinkle both sides of chicken with salt and pepper. Spread breadcrumbs on plate. Whisk eggs to blend in medium bowl. Spread flour on another plate. Coat both sides of chicken with flour, then eggs, then breadcrumbs.

Preheat oven to 350°F. Heat 2 tablespoons oil in large nonstick skillet over medium-high heat. Working in batches, add chicken to skillet and cook until brown, about 2 minutes per side, adding more oil as needed (chicken will not be cooked through). Transfer chicken to platter. Spread 1 cup sauce over bottom of 15x10x2-inch glass baking dish. Arrange 1 layer of chicken over sauce. Spoon 2 cups sauce over. Sprinkle half of mozzarella, Parmesan, and Pecorino over. Repeat with remaining chicken, sauce, mozzarella, Parmesan, and Pecorino. Bake until cheeses melt and chicken is cooked through, about 20 minutes. Sprinkle with parsley and marjoram and serve.
