These chicks are becoming more active than ever. In the next two images, we see that a chick appears to be trying to meet Mum half way as she comes in with food. As a result it is well and truly out of the nest cup.
This is 20 minutes later and another chick has got out for a stretch.
More wing flapping.
Another visit from the woodpecker.
Just after 9pm Fluffy thinks about settling down for the night. But no, the chicks are now getting much too uncomfortable to sit on. She reverts to her old habit of going up to the attic for the night. They think she should still be feeding them!
Five or six days before they go!
