Baby Ringnecks

Three out the four Ringnecked eggs have hatched!!!! My female Nelly has been spending time inside the nesting box with my male Nippet and he has also been inside the box with the new chicks on his own.
Nelly seems to be more aggressive towards my neighbouring Princess Parrots trying to attack them when they are too close and Nippet seems to be strutting around the cage displaying.

My female Bourke Parrot has abandoned her eggs unhatched again. The Scarlet chested Parrots are already trying to use the box she was in. All my smaller parrots prefer the larger parrot box as apposed to the smaller budgie size boxes for breeding.
