This shows Daisy's 9 eggs in Box2.

Again, 9 eggs!

A nice picture of Daisy's nine eggs.  Bluetits' eggs are a very pale brown with dark brown speckles.  They are quite tiny, being about 14mm long and 10mm wide.  (My Field guide describes them as "Smooth and slightly glossy.  White: very variably marked purplish-red, light red or reddish-brown as fine specks, small spots or variable blotches; often sparce and frequently forming a zone around the larger end.  15.6mm x 12mm")

All I can say is that the eggs I have seen, which are the unhatched ones still at the bottom of the nest cup when the chicks have fledged, are smaller that this!

Those look pale brown to me - not white!

Clearly 9 eggs.  The blotches are all over these eggs, not concentrated at one end.

Clearly there is a lot of variability in the look of the eggs!

Daisy has nine eggs too.
