It's been several days since my last post because not much has been happening except for the usual routine of feeding, removing poop (and presumably fleas) and sitting on the nest. That was, until yesterday. The sad news is that we can only count seven chicks now when there had been eight alive a couple of days ago.
The last egg did seem to take a long time to hatch and the chick was obviously a lot smaller than the others - perhaps it couldn't compete for food in the rough and tumble of the nest. We don't know if it's the last chick than has died or another one, but we're fairly sure it's gone and it looks like it might not even be in the nest any more.
Of the remaining seven, six seem about the same size and pretty active but there is another one which looks a bit smaller and it seems not to get fed as often. Hopefully it will survive as the parents are doing their best in terms of looking after their brood.
