Cockatiel pair not feeding newborns?

Hi all!

One of my cockatiel pairs - Skyy & Sunny had 3 babies in September. They were well taken care of and two of them grew up and are hale and hearty. The same pair laid another clutch of eggs a week before christmas. However, this time when the 3 eggs hatched, they were neglected and not fed, even though the parents were inside the nesting box, and I only discovered this when I stopped hearing their chirps and looked to find 3 dead little ones, who may have been just a few days old at best.

Well, I emptied the nest and cleaned it up and I see now they've got another 4 eggs laid over the past week.

My question is, Is there any documented reason why the parents neglected and let the babies die? The father seems devoted but it's the mother that feeds babies initially and that hasn't happened. Any insight as to how this may have happened ??

I'm trying to prepare myself to handle things in case the mother doesn't. i've fed 3 weeks old cockatiel babies before but not newborns and the thought freaks me out. They're barely a few millimeters. Thanks!

so sad to hear about the little ones, what a shame.
sometimes for unknown reasons the parents do not feed the young.
If you feel confident that dad can handle it alone, then remove mom once they start to hatch, or monitor them very closely and see how it goes.
I know you don't want a repeat performance, and understandably so.
there are other breeders who may have come across this problem, so maybe they can offer some advice.
I breed cockatiels and have a pair here that are excellent attentive parents, then I have my gouldian finches that toss all their babies, which is a miserable sight to see.
best of luck, I sure hope they all survive.

The new clutch of eggs have started hatching! I heard a newborn baby's little peep a few moments ago! Praying that the parents feed the babies this time round!!!!:21:
