Pink Goffin Cockatoo
My 6 year old Goffin Cockatoo has suddenly turned pink on her chest. She used to be white with pink undertones, but her chest feathers have turned downy instead of like regular feathers, and they are all pink. She eats a pellet diet with dried fruits, vegetables, and nuts added. I've also noticed that the feathers on her back between her wings are nappier than usual, as if she's been stripping them with her beak. I've not noticed any plucking behavior. Can anyone help?
