I have a flock of 5 hens in my suburban back yard. Roosters are NOT allowed in our city limits..... This morning I looked out the window and saw my "alpha" hen up on a roost bar in the run, CROWING. Or making her best effort. LOL! Yes, I am SURE she is a "she"--I know she's laid eggs, and she doesn't have the right feathering for a roo. I've heard that hens can do this when they get to the end of their laying years and their hormones shift....but I wasn't expecting it from my girls this early! It's not really that big a deal, except I don't want my neighbors to turn me in for having a rooster!
