I have a small flock of 9 hens. One of them lives in the house. The one in the house did not lay an egg today, but I got 9 eggs. I have two hens that lay white eggs (Leghorns) but I got three white eggs today. Is it possible for chickens to lay more than one egg in a day? I could have sworn that I collected every single egg from yesterday, but maybe I was wrong?
