Then noticed a few big flies hanging around the aviary and then a smell

Two days later and I havnt seen the parents in the nest, they stand on the perch outside, peering in while the chicks go wild inside, begging . I saw the babies last night heads poking out the nest, thats not a normal thing for them, a little something in the crop, didnt see them this morning, had to check, didnt look like any food had been delivered.

Edit 1... panic MIGHT be over, Ive just seen the cock go into the nest, not long enough to feed anyone but at least he went in.
But ideas and suggestions would still be appreciated, in case it all goes pear shaped

Edit 2...



Im thinking it might be a good idea to remove her.

As above any suggestions etc etc
