Pippa has definitely started to incubate her eggs.
Harry has taken advantage of the normal morning mealworm feed, to bring one in to give to Pippa.
Sometimes male bluetits have difficulty in actually passing a tit-bit such as this to their partners. There doesn't seem to be any problem here though and Harry passes the processed mealworm over to Pippa quite easily.
With a bit of imagination, I think you can see 11 eggs here.
Another mealworm for Pippa.
Well, is this 10 eggs or is it 11?
Well that settles it - Pippa has now laid 11 eggs. Since she started incubating them yesterday, I doubt that she will lay any more.
