If the scrambled egg recipe makes too much, you can always save the leftovers for tomorrow. But if you want to simply cook less eggs, you can do that too! Keep the butter or oil amount the same, then whisk together 1 egg mixed with 1 Tablespoon of milk or 2 eggs mixed with 2 Tablespoons of milk.  Adjust the salt and pepper to taste. Fewer eggs will cook more quickly, so reduce your cooking time and keep a close eye on them.
