Ouch! Time to get started on showing him who is boss. First, find or buy a pair of comfortable boots that you like and find comfy and will preferably wear to the chickens every time you go out. I notice that my rooster hates bright colors and black. My brown boots are the ones he likes and won't attack me with. When you go out and he tries to spur you, hook your boot under his chest, lift (not too high), and throw him backwards gently. He will continue rush at you for a while, keep hooking and gently tossing back. Eventually when you hold your boot up to his face, he will jump away. When you walk, he might drop his wing and circle you. Let him do this and he will become bored. If he pursues the matter after a while, grab him and push him down so that he is squatting, this is submissive behavior. Continue to do this until he walks away. When he starts to walk away, pursue him until you feel you have gotten your point across. Never be cruel, don't hit him, scream at him, or kick him hard. When you are hooking under his chest, be very careful that you don't accidentally kick him too hard. This can be easy to do, but always keep control on your leg. You can wrap duct tape (or gorilla tape) around his spurs to blunt them and prevent spur wounds in the hens and injury in you. Always keep you face up and away from his face and until you know he knows you are the boss and he is not, don't squat down in the pen and give him access to your face. Be careful when picking up the hens that they don't squawk and draw his attention. If he does come over, you can toss the hen gently in his direction to distract him so you can get your bearings and prepare for an attack. If you cannot show him that you are in charge, it is best to get rid of him to protect yourself. If you do want a rooster, Australorps are super friendly, and you can have more than one because they aren't known for fighting among themselves. If you can show him that you are in charge, don't let up your guard in the pen and don't let other people in the pen when the rooster is not being held by you, or shut in the coop. Good luck! Oh, and don't forget to put some disinfectant on those cuts, the rooster's spurs are probably very dirty!
