It appears that they may be old enough to use the breast feather technique. On dark feathered birds, the breast feathers of hens have a light bottom edge. In your second pic, the hen appears to have light strips on the bottom edge of her breast feathers. Males will not have that light edging but will have the bottom edge of the breast feathers the same color as the rest of the feather. It appears that your first pic of your claimed tom also has light edging to its breast feathers indicating that it should also be a hen. The first pic appears to have the mohawk also associated with being a hen.This is a male upclose.
And this is what the majority of them look like.
