Question help

In the last newsletter I had a question from a reader asking:

“Please could somebody tell me why my cockerel Fruitcake behaves in a strange way?  He chundles away to himself when I approach the run and when I enter watches me closely. If he gets a chance he runs sideways into me at highspeed and sometimes pecks my feet.  I saw him run sideways into the hens this morning, so it is not just me.  He also makes a very loud cawing noise, like I have not heard before.  May be he is a looney tune.  Does anybody else have any experiences of this please?”

Does anyone know why the sideways run? There is obviously a dominance issue going on, but the sideways running I have never seen. Would really appreciate any help as I am a bit at a loss 

And what Joy forgot to tell you was that when her boys do this, she imitates them and it confuses them!

And now I do it when Bertie Rooster sidles up to me!!!     It is funny to see him.  He's completely confused!!

Bless  None of my boys have ever been allowed to get big enough for mating rituals  Blackie was the only one who got old enough to deed do and he never seemed interested 

Obviously Fruitcake thinks his human mum is a potential mate
