The Japanese Tit chicks made a desperate appeal to their single mother...(May 21-22 2022)

This mother is quick to give up. She needs to try a little harder.
The Japanese Tit chicks made a desperate appeal to their single mother...
The father did not return today.
A male is singing nearby, and I can confirm that the mother and male are working together outside, but I am not sure if this male is the father. And he never comes close to the nest today... (what is this behavior all about?)
The chicks were not settled in the mother's tummy and were desperately demanding to be fed.... In the end, two of the chicks died that day. That left us with three chicks...
What can we do in this situation?
I have received calls to place millworms near the nest box, but this is a vacation home in the mountains and insects are abundant here, so I did not dare to add more insects. One of my motives for setting up the birdhouses was that I wanted them to eat too many insects...Also, if the millworms spilled outside and multiplied here, that would have other effects.
So...I decided to leave a bucket of live Kamadouma, which I could easily collect. They are growing in large numbers under the floor again this year, and they are getting bigger and bigger... I hope this helps a little...
But somehow, I think the problem with the current situation is more about the mother's feelings than the food. Of course, the father who stopped coming is the biggest problem.
