We have a 6 month old Australorpe. We have raised her since she was just a few days old. Her and her sisters have always been so sweet, especially around my 8 and 11 year old girls. Our girls love feeding them and simply playing in the backyard around them. In the last few days our Australorpe has randomly ran up to my 8 year old and jumped at her, scratching her legs to the point they have bled. And just now, when I let them out of the coop, she rushed out and did the same thing to me. I am not sure what has gotten into her. How do I make her stop? Help!
