This morning I found one or our hens hiding and holding her head very oddly. I think it is wry neck from what I have read. We feed them almost exclusively layer pellets, so I don't understand it being a lack of a vitamin, but we did switch companies a couple of months ago. We have a couple of roosters, though that are crazy this spring. Could it be from a rooster trying to grab her? She is a Red Ranger and our friendliest one well loved hen. I have black oil sunflower seeds that I could give her. Should I? She has been moved away from the flock and has her own water and food.
