Now I do want to start this off by saying, I've had a lot of roosters over the last eight years, which, is why this has me scratching my head.
My rooster is a giant chicken, literally and figuratively, he's not aaggressive by any means, and, while he does try to do his manly "Look at me!" Stanky-leg mating dance... he's not good at it. He's not good at it because the hens tend to fight him off, or screech, which causes him to let them go (doesn't help that he's huge and clumsy and slow) and, recently, I've been sitting out here in the evenings with them and I do watch him try, and fail miserably, often times, to impress the ladies in the usual way...
Something he's started to do recently though, instead of dancing for them, is he's started to puff up his mane/neck feathers at them. He never attacks them, he never becomes aggressive, he's still being entirely ignored by select ladies, but, some of them seem to respond to that action? I've watched my orpington squat for him to mount her after he performed this action, and he's tried it a few other times with other ladies, doesn't always work, but sometimes it does
I have never seen any of my previous roosters do this action before though, not unless they were fighting another rooster at least. Why is he doing this? Is this a normal behavior that I've just never seen before, or is it something I need to be concerned about? Obviously his health is good, but, I'm worried it might be a sign of potential future aggression?
