Hi! I recently just got 5 new baby chicks and they are a little over a month old today. I am hoping that they are all hens because where I live I cannot have roosters. I noticed today when I had my chickens in the backyard that three of them were play fighting and being aggressive. The barred Rock has very big legs and is bigger than all the other chickens, and is also the most aggressive. She(hopefully a she) always pecks me and runs away from me whereas all my other chickens follow me and think I'm there mom. I also have an Americana and a polish bantam which I think might be roosters! Help!
