Hello. As I was reading here today, I noticed a comment on feather color. My peach faced lovebird, Emerald, is 19 years old now as of May 1st. In the past few months I’ve noticed red feathers underneath her green feathers. Back of head, belly. I thought maybe it was a loss of melanin in her feathers from old age. But I read it can be a sign of liver disease. She seems her usual self, obviously not as active as when she was younger. She has a vet appt next Friday. Can I do something about it if it is liver related? Is it manageable? Are they in pain or suffering? Thank you for your thoughts. Just want to make sure my aging bird is ok.
