Is my rooster trying to mate with me??

[Serenia]

My buff orpington roo is around 4 1/2 months and for the last two weeks he's been pecking my hands and trying to mount it. It is not very nice at all considering he draws blood and scratches very hard. He does the same to my feet if I am not wearing boots. He was always very nice to me before and followed me everywhere. He does try to mate with my four hens too and is not very gentle to them either and they are missing lots of feathers. They have not started laying yet and I am afraid they are too stressed out to do so. If this problem isn't resolved soon I will have to give him away.So is this normal behavior for a hormonal roo? Or is this a sign of aggression?
