Our Buff Orpington has been laying fairly consistantly since she was 19 weeks old, still waiting for our Buff Brahmas to lay they are 22 weeks old now. Yesterday my BO layed me a white egg... I thought one of my neighbors was playing a joke on me taking my lovely brown egg and replacing it with a white. Our eggs so far have been small, and very egg shape, the last few are larger and more oval, the white one is throwing me off. I am certain its from the BO since I saw her in the box yesterday. My BB's dont appear to be near laying yet. Thoughts? Does egg shell vary from time to time from one chick?
