I have a big problem with my rooster too, he was so sweet for a long time until now he chased me down my yard trying to attack me! My mom came out and helped though and it's bad because he had never done this before, all though I herd from my cousins that he attacked one of them, and there is also 3 little kids that love my roster so much they think he is the coolest so if they try to pet him he will now bite you wich will he hard for the little kids☹
Please help me.

I'm sorry, but if he's attacking you, he's likely going to attack those little kids, too. Imagine how much damage he can do if he goes after them with his spurs. They'll be at the same level as his face. Please don't take a chance on a little child getting hurt. It's a huge liability - especially if they are visiting. Your parents could be liable for any medical bills caused by an infection from an injury from him. He's either going to have to be locked up when there are children around, moved on or put down.
