I have a video but I guess the file is too large to post so I'll post screen shots of the video.
In the video the rooster Pancake keeps circling the silkie Fern and then jumping on her, attempting to
grab by the neck and pecking. Fern is standing in one place in the middle and jumping/fighting back. So what's going on here? Is this a fight for dominance...do I have two Roos or does the rooster want to mate with her? I'll post pics of Fern in the comments. She's missing some head feathers from her recent fight with Pancake.
