After the appearance of the first egg on Thursday, yesterday was full of anticipation, but the second egg failed to arrive. The female spent extended periods on the nest, adopting postures that suggested she might be about to lay (as below),
Tuesday saw the appearance of the third egg, visible to some lucky webcam viewers at around 7 this morning. Given that the second egg was laid between 8 and 11 on Saturday morning it seems that there was a gap of about 70 hours between eggs (assuming it was laid early this morning, with early mornings apparently the preferred laying time), at the upper end of what is quoted as the normal range by experts.
A pleasant surprise this morning to find that the fourth egg has hatched to give us a full brood. Even when the adults leave the platform, as they are now doing especially around feeds, it can be hard to count the chicks.
