Hatch at last and a first feed

Update Sunday 27th: it's been quite clear for some days now that the other two eggs won't hatch and have been abandoned.
The two chicks are being well looked after by the parent birds and are growing fast......
Lots of Wendy's video clips showing feeds can be found in the comments.

Update Monday 21st pm: second chick has hatched!

Screenshot by Kate of both chicks:

Video by Wendy of second chick revealed:

 
After what seemed like a long wait, a chick was spotted just before midnight last night (19th).
The screengrab below was captured this morning by Helen, one of our dedicated watch point volunteers.

Here's a video by Wendy showing the first feed:
