One of my hens has started acting strange. She has started holding her wings out from her sides. ( they occasionally do this When it’s really hot out, so I wasn’t that concerned about that) she walks around just fine but when you pick her up and sit her back down, she does something strange with her feet, like she can’t move them or something. She just lets her feet go limp when you sit her down. She also acts like she can’t balance and get on the perch at night. She’ll get up to the nesting boxes after continuously flapping her wings stumbling up the ramp then I have to help her up to the perch. Also noticed I was short an egg, but I’m not sure if it was her or another hen that didn’t lay. (They also sometimes skip a day)
