--- End quote ---
On October 16, the chicks came out of their small nest box onto the ledge, where Mom continued to brood them, and both chicks were moving around. They were being fed and cared for.
By the following day, one of the chicks had become ill. He/she did not look well, and was having trouble opening the beak to be fed. Very sadly, the little one passed away yesterday. I am not sure of the cause, but it may have been Trichomoniasis, or possibly a toxin of some kind. In either of these cases, the second chick would also be at risk, but has appeared okay so far.
Mom has been sitting on the edge of the ledge, and has not been brooding the surviving chick when I have checked the cam.
I will update the Melbourne thread a bit later.

What happened to the second baby in Melbourne?
burdi:
I’m not about to draw any conclusions regarding Cilla's last post as it doesn’t provide sufficient information (in my opinion), so I’ll check back later.
burdi:
The chicks were snuggled together and sleeping before the screen froze at 0814 hrs and then went black.

Update - Sibling aggression
Published 15 October, 2017 | By Cilla Kinross
I hope this doesn’t keep up. The older chick Marragaay had real go at the younger one, Bali, with considerable blood loss. I was just thinking how well they were doing. I was trying to get up to date, but was only up to noon today, so I decided to fast forward so I could give you an update, when I saw this.
Bad blood between siblings
VIDEO 20171015 sibling agression
They are now cuddle up in the corner as if nothing has happened, but Bali is very quiet (but moving). Mum is sitting on the ledge. I haven’t observed this behaviour before in nine years, but it may not be unknown. Bickering yes, but not drawing blood. I’ll check and see how much much prey was brought in this afternoon tomorrow, but I’ve had it tonight.
The only other thing of note to happen is that it’s possible that a couple of bats were brought in as prey very early in the morning. I can’t be sure as the images are not great.

I've omitted a video as well as a couple of pics which are similar to the first.
