My hen is about 9 months old. I found her about 10 days ago on the bottom of the coop not able to walk, she was flapping her wings trying to come to me. I picked her up brought her inside. Nothing noticeable at that time with her legs. She has been inside this whole time. She started walking a few days later so I put her back outside & watched her. She seemed to be fine but didn't plan to leave her outside but she chose to walk in the house when I opened the door. So she walked around & found a spot to relax. I left her & put her in her cage a while later. A few days passed & she seemed perfect. Still eating & drinking fine! I put her outside & left her for about an hour & when I went out to get her she was on her back, feet up & head twisted. I swore he was dead! I picked her up & she was alive. I put her back inside in the cage & she seemed fine. So now 2 days after all that she is not standing at all. she is scooting around in the cage to get water & food. She is not even trying to stand. I lift her & she wont stand. She does have some poo on her but I think that is from sitting in it. I am not sure she has layed an egg ever. I have 2 of her kind & there has been blue eggs but not sure if it was from her. She has not layed anything while inside. They are feed layer pellets. She is alert & eating. No other visible signs.
