I only had a quick look at first as Mrs C was still on the nest but later I popped back with the camera and took a quick snap. I think I can count 8 but it's very crowed in there so maybe there are 9 and I just can't see the last one.
The nest is amazing. It fills the box but the actual bit the babies are in is only about 2 inches across and the babies are about 1.5cm big. They're going to get very squashed in there real soon.
