I have 2 silkie chicks. My girls have named them Lightning and Thunder. They are only about a month old, but I am thinking that Lightning is a roo, and Thunder is a pullet.
This is Lightning. Notice that stance!
This her is Thunder. She is showing signs of being a sizzle. I also think she is more likely to be a pullet.
No matter, I love them both. I would rather have girls, but I am okay if one is a boy. All of my little chickies are such cuties!
