I have two (supposed-to-be) pullets that are about 17 weeks old. They run around together, forage together, eat side-by-side, and get along wonderfully. They were purchased as chicks and kept in the brooder together. Today, I witnessed one of them jump up and kick the other one. Both of them flared out their neck feathers at one another. Having two roosters, I am concerned. My roosters exhibited this behavior when they were very young. None of my hens have done this. -just wondering if I have a roo rather than a pullet or if others have experience with hens doing this sort of thing. (They immediately began running around together and scratching about the lawn after their brief skirmish.) Anyone else have kicking pullets/hens???
