I have a 2 year old Salmon Faverolle hen, Sunflower, with a weird beak thing going on. On the right side of her beak, there is a small cut in her beak, which I noticed a few days ago. There was a little bit of black near it, but today I noticed that the black has stretched across almost her entire beak. She has no other symptoms. Is this just dirt or should I be concerned? Is there something I can do??
