Preheat oven to 400° F, and lightly spray a 12-cup muffin tin with non-stick cooking spray.
Mix the first 8 ingredients together in a large bowl.
Spoon potato mixture into each prepared muffin cup until about 1/3 full.
Gently press the potato mixture down in the middle and up the sides of each cup.
Bake until golden brown, about 25-30 minutes.
If the nests have puffed up too much in the center, scoop out a little with a teaspoon.
Spoon a few tablespoons of scrambled eggs into each nest and top with chives.
