IMO,there is nothing wrong with a. Friendly rooster,I raise all my roosters and hens to be friendly a and have not came across this issue.You must earn their struts as they must yours .Everytime he attacks spray him with water hose.You should have been dominanting them way long ago.Whne walking straight,neevr walk around them.Walk taright through them so they know your he boss.Move freely never act afraid or concerned around them,they will use that as weakness.Do these steps with all the non aggressive ones and you shouldn’t have to worry about their hormones driving them to you.If all fails for other rooster,if you can’t cull him,find someone who can,or give him to someone who is willing to deal with his behavior.
