Yesterday I thought my Cuckoo Maran must have laid her first egg. I found an egg that was larger than the rest, smoother and darker. So, my first thought that it must have been her. Well this morning when I went out to the coop, to my surprise Roxy, one of the BO's was just getting up from laying an egg and it was the same egg from yesterday morning. I am slightly confused. The BO's eggs are usually lighter and not quiet as large. Now all of a sudden this BO is producing quite large, and darker eggs? How does that happen?
