Nearly a year ago we inherited a group of chickens; they were about 6 weeks old. One of the Delawares ended up being a rooster, and we decided to keep him. Up to this point he has been pretty low key. He recently has been hard on his favorite hens, which made us consider culling him, but we we had not yet decided.
This morning he jumped me from behind and then charged at me again before submitting and walking away. We have a toddler that likes to be outside just as much as our chickens
, so there is no way that he is allowed to stay now.
This all made me wonder about rooster aggression. I’ve read plenty of good stuff on here about nice roosters, so I know they exist. But can people that know rooster behavior tell me:
-How long does it take for aggression to show? Does it usually take a year? Less, more, or just whenever?
-Does the aggression ebb and flow with hormones? Are there hormonal cycles for roosters?
-Our guy used to mate with the whole flock—well, except for one who was savvy and could out maneuver him. Now he’s down to just 4-5 poor girls. Is this typical?
-I am guessing on this, but does aggression have nothing to do with capability to protect the hens? He sucked at it—hawks could be circling his head and he was clueless.
-Are roosters not always at the top of the pecking order? We have a couple of old ladies that I think rule the roost. He pretty much avoids them.
-Are there breeds that are more likely to be aggressive? He’s a Delaware and we also have a 4 week old Marans male in our brooder that I’m wondering about now.
-Are aggressive traits genetic? Just this past weekend we hatched some eggs that he fertilized.
Also, can someone share what to do if a rooster attacks? I acted instinctively and roared at him and jumped toward him and he backed down. I just didn’t know if if was better to flee or fight.
And just so you can match a face with the crime, here is the offender. I have to say, I won’t really miss him
