I think one of my hens has been attacked by something, although I cannot find any wounds. When I went out to the coop today, she was walking very slowly, and squatting just a bit as if she was trying to lay an egg or poop. I let her do that for a few minutes, nothing happened, so I picked her up to examine her. She is my sweetest hen, about 8MO, and has always allowed me to pick her up, but usually she wants to get down after a few seconds. Today she let me hold her and pet her for a good 15 minutes. When I put her down she went off into the tall grass and laid down, also not normal. I went into town for a few minutes and came back to find her still walking slowly, away from the other 6 hens and one rooster. I picked her up again, and held her for another long time, petting her and also trying to look for the problem. Her vent appears normal, but her one wing has the feathers out of whack, and her tail end has the feathers kind of messed up as well. There are no wounds that I can see. The chickens are free range during the day, so she could have been attacked by a cat or something, but I would think I could find a wound if that was the case. Do you think it may have something to do with the rooster mounting her and being rough? The only reason I think this is because my husband saw the young roo mount her about a week ago for the first time (his first and her first, as far as we know). The rooster is normally very sweet, but he's at the very bottom of the pecking order. He was added a few months after we got the 7 girls. He is about a month younger than they are, and still hasn't even crowed! Maybe he is trying to move his way up and assert himself? These are my first chickens, so any advice would be much appreciated. For the moment, I have my Sweetie in a rabbit hutch in the garage. She happily ate the grapes I gave her, so at least she is eating. Mostly she seems puzzled as to why she is there. Not sure how long I should keep her separated, or if that is even necessary?
