UPDATE Her crop is empty now, I think and now she really can't balance herself very well and lies down. I will bring her inside but I wish there was a magic answer. She is quieter than normal and didn't protest as much as she should have when I picked her up to look at her ears. She only scratches the right one and then kind of falls to that side. I have seen her eat and drink a little. She is on medicated feed, is vaccinated for Mareks and has always had vitamins in her water. The other 4 chicks are fine, so far. She had watermelon, her crumbles and a little oatmeal scratch today. I'm really worried about her. Do the symptoms ring a bell with anyone? Those are the only things I have noticed and I first noticed them today. I will be very grateful for any suggestions.
