From here it looks like you have a Blue Runner and a chocolate Runner . Could be my computer too. What a precious pic.I'm not sure if the one is a choc but she did look a bid black/charcoal as a baby and kind of goes from darkish to greyish.. and the grey one was not grey as a baby and she is getting lighter as she ages. My dog has taken on the duty of surrogate Mother and she stresses any time they are separated or yelling. All my animals love eachother and live peacefully within the family, 2 cats, 3 chickens, 2 dogs, and now 4 ducks
