Will we get an Easter egg?

(Blog post updated with video)
With Easter being so early this year we stand a better than evens chance of getting a first egg laid before or over the weekend than in most other years.
For some unknown reason, our Derby female, despite having laid eggs in ten previous years, lays rather later than many other presumably younger females elsewhere.
Already as I write this on Maunday Thursday (24th), we hear (thanks to our super-comment sender Kate in Devon) of eggs at Nottingham (4), Sheffield (3) and Exeter (1).
The last two years she had laid her first egg on 29th March (ie next Tuesday) so perhaps she will just 'miss the boat' as regards Easter.
When she does lay it will be her fortieth egg....quite some achievement!
Usually she lays during the night and therefore under the infra red camera lights which make the eggs look white.
In fact, peregrine eggs are usually a lovely brick red colour when seen in daylight, with varying amounts of darker blotches.

Our female has laid four eggs every year since 2006, her first, when she probably laid three (she certainly reared three chicks). That year there were no cameras so we can't be sure there wasn't an addled egg which failed to hatch, and the birds' legal protectoin prevented us from looking over the top to count them from above.
The gap between eggs is usually about 2-3 days so her clutch will not be complete until over a week after she lays the first egg.

Full incubation doesn't start until the last egg is laid, though she may spend time covering her eggs before that if the weather is particularly cold. In fact, the early eggs can withstand going cold so we don't need to worry about them being left uncovered.....it is normal peregrine practice to do so!

This delayed start to egg incubation means that the eggs all hatch out more or less together, though sometimes there is one which takes longer to chip.

However. peregrines are great parents and will ensure that even a smaller chick gets fed and thrives.

Of course, we shouldn't really count our eggs before they hatch...and certainly not before they are laid, so we need to watch and hope that we do indeed get an egg for Easter (or soon after!).

No doubt our eager web cam watchers will put up comments as soon as anything happens. So keep an eye on the comments as well.
Some clever viewers have even been capturing their own screenshots and videos of the webcams. This one by Wendy Barrter was shared on YouTube:
