Have two chickens almost 1 year now that have episodes where they tilt their head to the side and run in a circle chattering their beek. They eat but are very thin witch worrys me. They are the lowest in the pecking order and get bullied by the other chickens smaller and the same size as them. They love to hang out with me when they are free ranging. Like siting on me and scratching my pants with there beeks. One of the hens started this after she got attacked at 2 months or so by a dog he bit her head witch made blood in her ear. The other was 3 months or so when I notice her doing the same thang. Don't know what happens to her and lap dog was not any where near Alkalight(the first hen) so L.D. could not be copping her.
