为什么我写的这个python程序运行不了？

x = 1
while x <= 100:
    y = 1
    while y <= 100:
        z = 1
        while x <= 100:
            if x*5 + y*3 + z/3 == 100 and x + y + z == 100:
                print('小鸡', z, '母鸡', y, '公鸡', z)
                z += 1
                y += 1
                x += 1

注意自加部分缩进
