Our chickens are doing a marvelous job laying eggs and Sugar Plum Fairy and I made a chart to keep track of who lays what when. The Plymouth Baird Rock (Velma) lays light brown eggs, the Rhode Island Red (Ariana) lays a darker brown egg and the Americana (Daphne) lays aqua eggs. This morning, we discovered a small brown egg with rough black spots on it and it is the same weight as the others. This picture shows the comparison between the oddity and the normal eggs. I have heard of chickens sometimes laying soft shelled or no shelled eggs for various reasons, but do any of you know about chickens laying a different color, shape and size egg?
