I have been reading on roosters and I'm a little nervous that my hen may be a rooster. I have 3 hens all 4 1/2 months. None of my other hens have large crowns or waddles and this ones is already very large. Also she is bigger than all the other hens and her feet are larger. She is a brown leghorn so I'm not sure if this is normal for this breed. Any info would be helpful. I don't know what to think since this is the first time I have had chickens. Please let me know what you think.
