The chicks now look much more like bluetits. Their wings seem quite well developed, but their backs under their wings are still rather pink and bare. We have not seen all six at the same time today - we hope they are all managing to get their share of food and air. The female still delves down into the nest, almost disappearing on occasion. Once she emerged carrying a faecal sac from the bottom of the nest - presumably the chicks cannot always wait for the appropriate time. On another occasion, the chicks seemed to be taking a siesta, when suddenly there was an upheaval in the nest, and the hen emerged, looking somewhat ruffled. She really does seem to take her housework seriously.
Later - all six now clearly seen. If you are wondering where the sixth chick is, look at the bottom right of the picture where one chick has escaped the nest and is wandering around looking confused!
