New egg.

It will be interesting to see if the female blackbird lays more eggs in the nest. Usually it would be one a day. They pair are still feeding the 3 chicks. They are scuttling about in the undergrowth mainly so to get a picture is difficult.  I saw one make a short flight into the bushes so they are learning to fly. As soon as they can fly and feed themselves the male will drive them off. The parents most likely will have a second brood to care for by then.
