Lets start with the simple; roosters don't dance. Honestly, I've tried playing them all sorts of music, not even a twitch let alone a full on tango. They've got absolutley no sense of rythme.
Next, roosters don't care how big you are. If they did we wouldn't be expecting them to defend their hens and we wouldn't be reading all these posters from people who believe they are being attacked, who are in general much much bigger than a rooster, would we.
But, roosters do care about food; lots and they can be very particular about how food is presented to them and more importantly their hens.
Basically if you are feeding their hens then as far as the rooster is concerend you are competition. If you are large and feeding their hens then your just large competition.
Given the average rooster doesn't break into the quickstep when you sing to him or play a danceable piece of music to him then it stands to reason that while you may think he's dancing he is in fact doing something else.
The art is to work out what he is doing.
One excellent starting point is to look to see if he does the same thing to any other creature, like your cat or maybe around the fishpond if you keep fish. After all, one generally isn't fussy about who one dances for once the rythme takes one.
You may notice your rooster does the same movements to his hens. Nope, not dancing; hens don't have a sense of rythme either.
What do the hens do when the rooster makes these movements? They don't break out in rounds of rapturous applause from what I've seen. They don't sit suddenly transfixed by the dazzling footwork either.
One might be tempted to think he's a horrid rooster trying to kick his poor hens about. However, if you watch carefully you'll notice that the kicking foot is on the opposite side to the hen and you in the case of him not dancing for you. I can't believe that all roosters don't know their right foot from their left, despite not having any sense of rythme, or which side of their body the hen is on.
If one watches the hens reaction to this not dancing move, you'll probably see that they move a little bit away from the rooster. The rooster may do it again and the hen will move a little more. Okay, the hen could just be warming up for a full on tango with her man but the only tango style reaction from a hen I've seen is when they turned round and given the rooster a right hander, or a foot swipe or two.
The move the rooster makes (nope, not dancing) is herding movement and roosters herd their hens. This is one of the ways a rooster manages to get their hens who usually have their beaks in some patch of grass or other with food on their minds to move. You may observe that if that doesn't work the rooster will flash his hackles. That's not dancing either. That's him telling the hen that he doesn't care how tasty that worm in the grass looks or how comfortable she is in the dust bath she needs to move, NOW.
The move is called the herding shuffle. A rooster only does this to his hens and occasionally to his junior offspring male or female. It's a you belong to me type of move. Not aggressive just like when your man, or women, slips their arm around your waist when out walking and gently steers you in some other direction, probably away from the shop window you've been standing at tempted to spend money you don't have.
Reasonably enough, should you turn around and try to beat the crap out of your man, or women, or whatever you identify as, the person who has just slipped their arm around you is likely to get a bit pissy. Roosters feel the same way.

Nope, it's not an article about dancing.
