We had our first blue egg today! The other egg in the photo we think is a "rooster egg", as we had 4 eggs on Thursday, all brown, but one was a funny shape. So we think the "rooster" laid it, and he is a she, whom we have named Frankie. We had a few funny shaped ones from our original girls when they started to lay, and this one is not blue, so it's the only logical explanation. Can't wait for some more blue eggs, to see if some will be bigger. (Little) Louisa is a fair bit smaller than (Big) Betty, so I'm wondering if this egg is from Louisa. It's only 46 grams.
