In our case, the chickens were surely first. In fact, in our first batch of girls we thought we would never see eggs. Yet, the eggs finally came. And we similarly thought with this group in the Fall that eggs were being hidden.
More importantly, my mother-in-law posed the most mind-boggling question: How do they do that? How does that little bird produce something that big nearly every day?
Egg formation is perhaps one of the most amazing processes I've ever read about. My fascination is perhaps because I have begun again to find them (one brown, one blue today!), and I marvel at what my girls do with all they eat.
