Preheat oven to 350 degrees F (175 degrees C). Grease a baking sheet.
Crush potato chips onto a plate. In a large bowl, whisk together egg and milk. Dip the chicken cubes into the egg mixture, then coat well with potato chips. Spread the nuggets onto the baking sheet.
Bake for 10 minutes. Turn nuggets over, and bake for 10 minutes more, until golden brown. Remove baking sheet from oven, and insert a lollipop stick into each nugget.
