Wasp has other roos (I have currently a total of 10 roos, all but 3 free ranging most of the time) out with him, and they were actually IN this morning while we were feeding (the puppies are stealing chicken feed, lol, so we feed in the coops right now, then turn everyone loose for the day, then they go back in for dinner and bedtime).
My son was just standing there, watching me, when Wasp acted up.
The others are very well behaved, and right now, Wasp is not the boss roo. He got dethroned by an older, wiser mixed breed. He was better behaved before Eyebrow (my kids are creative at names) took over. Maybe I will take Eyebrow away. Or maybe pen Wasp and a couple young ladies together and not allow free ranging for him until he grows up a bit more,
Wasp has always been "dominant" behavior-wise. Like I remember him pecking at our hands when we removed the feeder as a chick. The kids didn't want to hold chicks because of him, which was fine with me; they were always afraid of being pecked when they reached in the brooder.
I was having the kids squirt him with squirt guns, but they seem to have lost all the squirt guns. Must replace and try again. When the kids are playing outside, I tend to be out there and monitor everybody's behavior.
It's just the one SFH doing this. Not a single mixed breed has acted up. The EE roo is a delight. The Cochin roos are so good; a couple will let you catch them and carry them around. The Silkie roos are not incredibly friendly, but they are not aggressive. My other SFH are curious, but no aggression at all; I handled those ones little to none. I have two young guys I pick up almost daily that seem to be fine so far.
I like him otherwise, so I'm willing to give him more time to get over himself, but I can't have him attacking people. My goal is to have birds and people living together in happiness and freedom, so birds unable to live within those guidelines can't stay.
