My best friend who joined our family six years ago has a droopy wing, she can still fly but not really well. She preens the droopy wing joint. This morning stools were quite green. She just vented a runny one with blood. Any assistance would be greatly appreciated.

EDIT: I called the lady I got the bird from---she said not only does she feed this parakeet feed that has red food coloring, but she also offers cherry stone grit AND fed some fresh veggies last night. She told me that if it doesn't clear up by tomorrow to give her a call and she will take her...
