I’ve seen roosters mount other roosters multiple times before.
I completely agree. Not only on the cockerel (I see saddle feathers too) but on males mounting males
mounting behavior does not guarantee that the bird being mounted is a female; often it's a display of dominance and happens with either sex in either position
Me, who’s had birds for 10 years and doesn’t have a single memory of this happening with my birds (I feel like I’ve witnessed it once but I’m not sure if my brain is just making it up to mess with me):As for the males mounting males, that is just something that happens when a male needs to show the other male who is the dominant one.
