She sounds agitated as if something is not quite right somewhere along the line, perhaps she feels it is unsafe where she has her babies but can find no where to take them too or perhaps the dad is too close for comfort.
I would check that all is well in the nest taking care not to touch any of the little ones and if possible give her another box to take her young ones too if she feels it is what she wants.
Of course she may very well just be moaning about having to do all the work herself
