I was told each hen lays an egg a day. I haave 4 hens, and 4 nest boxes. I have one EE, 2 brown hens, and one barred rock. I was told chickens don't share nest boxes, the past few days, ive been finding 3 eggs in my EE's next box, two of which I know are hers. Theres either 2 blue eggs, or 2 blue eggs and a brown egg.
