Hi, We have a new baby budgie that we've had for a week now. We've noticed that when she gets wet she gets spots on her belly that are brownish (she is bright green). They seem to go away as soon as she's dry. We thought she might have scratched herself on a small sandpaper perch we had in the cage and the spots were old blood, but as soon as we thought that we removed that perch and yet it's still occurring.??? She does not seem ill or act injured at all.
