One of the two hens I picked up two days ago seems to be aggressive and by aggressive I mean she doesn't fear anything and as soon as I walk by the pen she comes over and if I put my hand near the fence she will appear as if she is going to peck at me. Before i went to add food to their bowl and as I got in the run she came over to the door and I was afraid she was going to make a break for it so I guided her away from the door with my hand so I could get in. After I was in she started pecking at my boots. After that she stayed next to me and then walked in front of me as I was crouched and started looking me up and down trying to get closer. I had a button down shirt so I was thinking she was trying to get to the buttons? And my other hen just keeps her distance until there's food involved. Lol She was all fluffed up with her tail high before, what does that mean? I thought to myself that she looks like a Tom turkey strutting for a lady friend. Any input is appreciated.
