I am so sorry of you loss, *hugs and more hugs*. You did the best you could for her, and truly out your best foot forward! So sorry, this must have been hard. :hugsAvery
Can you brig her in for eh night in a dog kennel? That will be he bet thing of her so you can keep tabs on her. It okay to wake her up to bring her in.
Have you checked for mites? Are you sure she is molting, or jus pulling her feathers out because of parasites? All of theses symptoms point to mites or lice to me.
