One of my favorite chicks, Winter, is doing an odd thing with her head. She is some kind of silkie (that will be my next question). She does this when she is out on the ground with a lot of space. I have had chicks before, but i've never seen this! She gets down kinda low, and moves her head back and forth robotic like. Should i be concerned? She seems fine. I'll try to get a video, but she dosen't do it very often and my camers is almost out of memory. Thanks!!
