So I went down to the coop a couple mornings ago, and my BB red hen, Little Girl, was crowing!! I've had Little Girl for a few years now, and she's laid eggs, I've witnessed this. She's gone broody, she's everything a hen is supposed to be, so.... why did she crow?? I havent heard her ever since, but it was soo weird.... I just heard my roo's normal crow, and then this different voice, and saw it was her!! Weirdest thing ever!! I've seen this in peacocks, but it seems more common. Males make the normal, eerie calls (ee-aww, ee-aww, ee-aww!), and one day while in the yard with a peahen that was acting very strange...(she was on the other side of the fence, instead of flying over, she would pace ALL day, and I mean, ALL day, she'd wake up, pace all day, roost, then do it again the next day, and laid an egg in the middle of her now worn down pacing trail by the fence), she made the male sound and I was surprised.... Maybe some dominant hens take on male characteristics? Little girl is the dominant hen of the coop.
