Combine the ground chicken, carrot, onion, garlic, scallions, salt, pepper, and oyster sauce in a bowl. Mix well.
Separate the egg whites and yolks. Add the egg yolks to the chicken mixture and mix until well combined.
Place a spring roll wrapper on a flat surface in a diamond shape. Scoop about 2-3 tablespoons of the chicken mixture onto the lower third of the wrapper.
Fold the bottom corner over the filling, then fold in the sides and roll up tightly.
Heat the oil in a large pot or Dutch oven to 350°F. Fry the lumpia in batches for 2-3 minutes until golden brown.
Drain the fried lumpia on a paper towel-lined plate. Serve hot.
