Hi all! I can't figure out if these are roos or hens. I thought the one below is a RIR hen, but she is aggressive toward the other birds, mounts them and is 30 weeks and hasn't laid one egg. I couldn't get a good snapshot of her face, but I was hoping by saddle and tail feathers someone who is better versed could tell. She started to squat late in the summer, but when it turned off cold she stopped acting like a hen. This is my RIR rooster. Of that I am certain This is my sex-link and I''m not sure if she's a roo or a hen either! Gosh! I'm TERRIBLE at this!! I have 3 other birds I KNOW are hens as they came from friends. These were the only ones I'm uncertain about. Thanks for helping this newbie backyard chicken owner!!
