My Black Marans are now around 9 weeks old, and I'm trying to figure out if one of them is a rooster or a hen. This is the possible roo, at least it is supposed to be a roo. I won't be too upset if it is a hen, since I can always just buy a roo later. The next pictures are of the hen. I know she is a hen. Her comb and waddle are a fleshy pink. Above, the comb is a touch bigger and it and the waddle are more red.
