Thank you, everyone, for the advice and encouragement!!!
There are willow trees around where I live, so I will see about getting Yadira some branches. I'm also going to ask the vet to prescribe something for her.
I will look online and see if I can find the toy that she got caught on so that I can post it for you.
Right now I have Yadira in a bird carrier with a low perch, some food and water, and a hand-towel. In the last 24 hours she has become very steady in her ability to perch on one foot with the injured one stuck straight out behind her. She sleeps a lot, and I
think she has lost some weight, although I don't have a scale to say for sure. She is eating, though, and drinking. I have her next to my computer in the office where I work so that I can keep an eye on her. Fortunately, I have a very understanding boss and co-workers.
I got a bag of carrots today, thinking that maybe when she lunges at me I could give her a carrot. The almonds sound like a good idea. Unfortunately, in the week I had her before the injury I hadn't yet succeeded in getting her to try anything other than the seed mix she was accustomed to at the pet store. (It took weeks with my first cockatiel Lady Gwen.)
I am still very new to bird keeping in general, so your advice is greatly appreciated!
Jo, I read about your experience with the harness. That must have been terrifying! I'm glad it turned out okay. I've looked at those harnesses in the pet store and wondered about them, but I haven't been quite brave enough to try one.
Thanks again! I will keep you posted.
