I dont have BR's but I do have a few rude chickens. The Black Aust's are rude to me and the other chickens. Blacky is constantly picking/pecking on me just to annoy me. She's such a brat, she will purposely walk over to me just to peck me. I usually chase her away or sometimes I"ll scoop her up and tell her to leave me alone. Pony is my other BA and she is always pickin fights, she the smallest chicken but is not low woman on the totem pole. The RIR's I got, one is just a butt. Her name is Rosy and she is a trouble maker. She sits on the waterer and poops in the water( I fixed that with a tomato cage upside down), shoves all the nesting material out of the box, acts like the coop is hers and all must bow down to her, she seems to escape all the time. I tell ya.. if it werent for chicken personalities I'd be bored!
