I'm sure you're not the worst bird mommy ever.
You've been going through a stressy time, but now you'll make up everything they've been missing.
If you feed Dr. Harrison's it's not too bad when they don't get fresh food and supplements for a while.
My Paulchen (blue) is currently looking awful, because his female Yuki is plucking him.
Several times a day I hear his angry caw, and Yuki is sitting beside him chewing a little blue feather.
I met the Avian, but all I can do for him is giving supplements and misting him with Avix Soother spray.
What I also did is to buy a sun spot with UV light additionally to the basic LED lighning of the bird corner.
I think it has become a bit better already, hope so much that he'll get a new feather dress for Christmas.
