rays usually darken with age. is that a scar on its backbone
If I wanted another brown ray i would have bought another motoro for 100 bucks. I was hoping it would be more black then brownWhy would you want it to turn black??
Nicest black rays are very light grey hens but they are alot harder to find than black hens.i think your hen will turn very dark grey almost black. Most hens will go darker when larger I've only ever come across and seen a few nice full grown greys.
