Thanks for your thoughts. It's possible that she hears something calling outside like a fox, owl or bobcat, and the moon was full the first time so she may have seen a shadow through the black sheet that covers the cage. That she was searching under her wings last evening made me wonder about a spider or insect as well (I offered her a mealworm once and she was scared to death of it). I weighed her this morning (they brought the scale up with the cage) and she's down quite a bit since I last weighed her a few months ago - her other mom had trouble getting her on the scale. She'd also bought a 5-lb bag of pellets that may have gone south by now, although they don't taste or smell bad (I will order a new, smaller bag today). Her appetite for fruits and veggies is also down significantly. The vet is an hour away and Dewey will be less than amenable to being handled...the man who raised her told me she'd been once in 21 years
. I'll work on getting her weight up over the weekend, create a substitute for the pellets until new ones arrive, and take her to the vet if I sense that these adjustments aren't helping. Question - is it better to get high potency pellets if the bird is underweight? Thanks again for your guidance.
