You know what she just did? She pulled on a feather so hard that it stretched the skin of her neck out then snap! It tore out. It's terrible.... Safira - I can't stand watching it. I was under the impression that she just plucked while being boarded and that it wasn't an everyday thing. That's what the owner led me to believe.
Give her time - she doesn't know she is starting the next & better phase of her life.
Look at this from the bird's perspective - your original post was on Friday & you said you only had the bird since Wednesday. That is a VERY short time. Now it is like 9 days later, still a very short time. Folks who rehome birds have told me that it often takes 4 full seasons before the bird really settles in, so hang in there - the journey has just begun.
Maybe she really only plucks when boarded - and doesn't know, yet, that you are her new home.
By all means get that bloodwork done, but stay calm & don't expect immediate miracles.
If it helps to see this from a little further down the road, our Grey arrived 9 months ago with a fully plucked chest & legs. He stayed plucked for a while. People suggested we get him preening toys (they terrified him) or a phone book that he could shred in lieu of his feathers (it was too big & he was terrified of it, too).
But we gave him old paperback novels & they were small enough they didn't scare him, so those worked - he'd work his way through a book & we'd give him a new one & his feathers started to grow back. As his confidence grew, we could give him bigger books (that lasted longer). Now he is fully feathered, although you can look at some of the feathers & see the ends are shredded.
I am not saying he will never pluck - he still occasionally nips off a feather or pulls one out. But I think it gets less and less.
Again, keep an eye on her health & consult a vet, but time might be the cure, if she truly does only pluck when boarded. She does not yet know that you are her new home. Give her time to figure it out.
