Our 8-year severe female has been acting strange of late. These acts include snapping of the wings when at rest, over-preening and a strange little quick-step dance that lasts for 5-10 seconds. When distracted, this all goes away. From birth she seemed to be an over-preener but it's now to the point where she actually creates an open sore on her legs. The vet has looked her over and found everything to be fine - except for the open sores which we apply an ointment to - she is normal weight, blood and stool okay, etc. She eats well, spends a fair amount of time outside her cage, she is treated like a little queen, has lots of toys, lots of light and lots of attention. We're thinking it's boredom, but we don't know. Anyone have any ideas? HELP!
