God makes them this way, Big Sister tells me. Early in our egg adventure, when the hens wouldn’t stay put or use their nest boxes appropriately, I joked that every day was an Easter-egg hunt around here. Of course, all the eggs were brown.

That has since changed, with our recent additions of two Araucanas and a Brown Leghorn:

The Araucanas lay the green-blue eggs (and sometimes pink, I’m told, but none of ours are pinkies), and the Brown Leghorn lays the white. These particular brown eggs came from Whitey-Black, our Barred Rock.
They even match my new counter. 🙂
