Hopefully the treatment will take care of it and she will continue to improve. I think that we are all just bit reluctant to say what kind of worm we think it might be without being able to see it. I've had a couple of really sick birds from wormloads that took about a week to bounce back, one was impacted from them (large roundworm is what I deal with regularly), a few have had a secondary bacterial infection that I treated with amoxicillin. I thought the impacted bird was a gonner, but on the sixth day things finally started to move and she bounced back quick after that. So I worm regularly now, and rarely have issues. If she doesn't really improve then pictures of the droppings might help, may give ideas to anything else she may have going on. Sometimes more than one thing can happen, or things happen at the same time and it's coincidental.
