Young rooster behaving badly

[Altairsky]

I'm really sad to be this late, but in case anyone has this problem and reads this thread, I'll write down what worked for me.
My 7 months cockerel fought the 2 head hens. He would grab them by their comb and kick them forever.
I fixed this problem in literally a few days by separating the rooster for a day until the hens had a scab in their comb.
Then every morning, I would rub the hens comb and wattles with viks vaporub or any other flu cream that has the same disgusting smell/taste.
Apparently these flu creams taste like death to chickens.
In a couple of days it stopped the bad cockerel behaviour.

I love this. I have used Vicks to stop puppies from chewing things they shouldn't, as well. Think, table legs, another dog's ears, and a client's oxygen hose. Use your imagination.
