One of my 4 mo old standard cochin hens has some strange tail feathers, and I was wondering if it was normal, or if they are getting at each other? It seems like 1 or 2 of her feathers are sticking straight up. I am not sure if it is the other hens pecking at her, or if it is our rooster trying to be amorous with her. I got all of my chickens at the same time, so they are all the same age. She tends to have the reddest face of all of the females, so I think she is the most mature, and wouldn't be surprised if it was the rooster. Does anyone have these type of feathers on their hens?
