I checked the nest and sure enough it was empty.On searching the aviary I found one in the high branches...bottom one in the pic...

The other I found desperately trying to climb the wire flapping it's wings like mad...it didn't make it.This one is very tiny,luckily the weather is ok and it might make it. Although I've found chicks stand a better chance if they can follow the parents to beg.It's just sitting quietly hoping It's in a safe corner.

So one dead bicheno and two survivors up to press.
I had another experience today I don't want repeating....One or two birds decided to panic for some reason...this was taken up by all the other birds except the Rosa Bourkes which remained calm.All I heard for the next couple of minutes was 'THUD' 'THUD' as bird after bird flew at high speed into the wire.At least six did this and I finished up with several on the floor panting after their panic.
An hour later after I left them in peace, things seemed to be back to normal and none seem to be injured.
That was not something I want to see repeated...and what decided them to suddenly panic I don't know...it's a new one on me.
Oh...and Annague...I sprinkle diatomaceous earth in all nestboxes plus an anti mite spray.
