It turned out we had two eggs, and now they are fat little squabs (see in order of events, Pigeon culture, Pigeon news 2 and And now we have an egg). I’ve been photographing the nest every morning. If you click on the first image, you can follow through the days. We realised we had two eggs on July 6, saw the first shell fragment on July 17 (17 or 18 days after laying) and two squabs the following day. Most of the time there seems to be only one adult in evidence, until on July 23 we saw them change duty – the relieved bird promptly disappeared.
