I recently raised 50 baby chicks to 7 weeks old and I learned a great deal about their different personalities. I had EEr's, Red Stars, Black Australorps, and Barr Rocks. Each group displayed interesting personality traits. EEr's were very in my face. I had one little girls that would stomp up to me each morning and just tell me off. Later as they grew, they would jump up on the panel I put up to keep them inside, and tell me where to go and how to get there. Very funny. Barr Rocks, would come up to me too, but not to tell me off. They'd come up to say "Hi!, whatcha doin', can I see?" As they grew up they would jump on the panal too, but it was still just to say Hi and see what I was up too. Now if you don't have a lot of experience with chickens, you might wonder how I can tell a difference, but you can. Red Stars: Very active but doing their own thing. They didn't care what I was up to, just busy in their own little world. Black Australorps: Very quiet shy birds, would stick to themselves and others of the same breed. Rearly would go outside when it was nice, and if they did, they'd go pretty much as a group. Not very outgoing or curious at all. Now these could be the displayed personalities because of the situation I observered them in, but I thought I would share in case it was helpful to anybody.
