BO= buff orph right? not to be rude but Blanche is not a buff anything, she is going to be patterned somehow, where did you get them? and Blanche I say is a roo because of the wattle and comb development at the age~
in photo #2, I say there is a 50/50% the closest one is a roo, leaning on roo, in the background of photo#2, of the ones you can see the faces of the one to the farthest left is a roo, and the right is a 50/505 maybe.
Can you try to get individual photo's?
