Stress Bars on Baby Green Cheeked
I purchased a 3 1/2 month old baby Green Cheeked Conure from our local bird store. He/She is very social and friendly, and is acting perfectly healthy, eating, drinking and eliminating well, and playing with her toys and us.
My question is - she has some black stress bars on her wing feathers. I plan on taking her for a vet visit soon, but can you tell me what would have caused these stress bars on her and does this mean she is harboring some illness? Also, will they go away with good nutrition and a stable home environment?
