I just went outside and let my two 6 month old hens out this morning(they are both laying). When I came out to check on them they came running up to me as usual but then my leghorn bit my arm! I pushed her to show her I was in charge then she came back full throttle and flew up at my face! I flung my arms around to keep her from my face and hit her to the ground she got right up and stared at me with her chest out big. I ran inside then right away she flew up to the grill and started making crazy loud noises! It almost sounds like three unhappy clucks then a crow?! It's so loud I had no idea she could make this noise! I have no idea what brought this up? Out of my two hens she is always the nicest. Why did she do this and what can I do to stop it?
