I have been in touch with a couple of rescue organizations about Lucy's rehab. Again, keep the perches low and food and water dishes within easy reach. For a while at least, put something soft at the bottom of the cage so she doesn't go bonk. Cover slick perches with Vetrap. (3M is too cool for its shirts.) Try to find a cage wider than high, which is easier said than done, though I have one, and Charles (the bird) will fight to a feathery death to keep it for himself.
Lucy's new cage is not particularly high, but it looks like a palace to her.
It has rope perches, cholla perches, and a nice platform perch to sleep on or to hide under. Horizontal bars for climbing. So far, she pretty much hates it, but that's about half an hour's stay with no treats.
The birds and I have been burning up my credit card for online purchases.
Lucy and I are slowly coming back to a point of trust where she doesn't feel the need to chew my hands up when I touch her.
