Chicken Way 3D

Your task is to herd all these chickens into the chicken coop.
Remember, the chickens only follow you when they are collided with other moving chickens. They will move in herds and follow the path you draw down below. they cannot climb back up.
Too many chickens can cause traffic jams. The higher the level, the more chickens needed and you will encounter many obstacles on the way. So consider carefully before drawing your path.
