As far as I can tell four eggs have hatched in the main aviary.  The young make a racket when they would like a feed.  Despite that they are very hard to see (their parents have done a sterling job with the nest construction and camouflage).  The remaining two eggs may be from the charcoal pair (where the female died) so they may not hatch.

None of the eggs in the smaller cage have hatched.  I’m starting to get suspicious…
