My sweet barred rock hen, Beatrice, is acting really oddly around me lately. She keeps puffing up and almost separating her neck feathers when she approaches me or some of my other hens. She's also making a weird cooing sound when she does it. When i try and sit her in my lap and calm her down she makes the "there's a predator around here" screech as if the neighbor's cat came in the yard or if the big hawk flies over head. She hasnt always done this, it just started this week. I didnt really know why and was wondering if anyone could help me with an explanation?? Maybe she's about to molt?? It is pretty hot here around the 90's every day.
