Just in case anyone thinks I was interfering with this family. When I took pics of the chicks.The parents were both out in the flight.After day 5 they seemed to spend loads of time away from the nest probably because the chicks were safe and warm at 18c indoors. However I later found that the smallest chick facing the front was dead I always have my camera with me and the parents didn't mind me going in as I'm in there to replenish live food all the time. I held camera above the nest and clicked 3 times,went back into the house then put pictures on computer to see if any were good. I got this one. The other pictures were taken from 8 ft away and the parents were perfectly calm.
