I want to show you the picture of my little "hideaway" Fave.
(She was the suprise at the bottom of the nest this spring.) She is quite a bit darker than any of my others and not in the Fave pen. I, like you, will not raise a fuss with Ideal, but she's not a typical color at that age. Maybe the Fave rooster (her Dad) was a work in progress for darker roos..... but who knows. I can only assume she will lighten like my others did. If not, that's ok too. She's very sweet.
This is a roo. The males of this breed are the only ones with those colors. Silverish yellow hackles, mahogany body and dark chest.
