does mounting behavior always indicate a roo?

[rosegal]

This chicken is about 6 months old and today I noticed the mounting behavior on several hens. My husband swears that he has heard a crow in the morning....I have had it for about 2 months. Today was the first time I have seen this from this chick and now taking a closer look it really does seem more like a roo. It is also beginning to have ploom feathers on the back end.

if you hear a crow,
you have a roo..

but not always does mounting mean a roo
it could be a confused hen

A dominant hen will sometimes assume the role of roo, hard to tell without pics.

My little girl Boston Terrier mounts her brothers. And all three are "fixed". It's common in all the animal world to show aggressive dominance.
