I think one of my hens might be sick. She was still standing in the roost at 8:30am, the rest of the ladies were let out at 5:30am. By 9:15 she was out just standing by the water and she hasn't moved more than a few inches in the last hour and a half. I'm not sure where to start or what to look for! This is my first flock and my first sad hen! I took a picture because her comb is leaning to the side and looks discolored. Please help!
