My two Barred Rocks have been laying for about a month and a half now. I keep pretty detailed egg records, and they lay a 1.7 oz to 1.8 oz egg almost daily. Today I saw one of them come off the nest, and she'd laid a tiny egg - I weighed it, and it's only 0.7 oz. (Looks otherwise normal; just very small!) I would have been excited and thought I'd had another layer, but since I saw the BR in the nest, I know it's hers. Does this happen every once in awhile? Before today, the smallest egg either of them laid was 1.5 oz. Thanks!
