I have 5 Blue Orp/buff Brahma chicks. 4 are light to medium blue gray. One, a shy little chick, had almost black down, now is growing in what looks to be almost black feathers, no blue or gray at all, and the down on her chest is like a light tan. I guess my question is Speckledhen, Is it possible that this chick had different parents? She is very timid, too, unlike the rest. She never comes running for yogurt, but will take it if I offer it to her separately. And she sleeps with the silkies. I named her Chloe, she's so shy. What do you think?
