Ok we have this two year old hen. She has been laying, eating, being normal until the last few days. The first night she seemed lost. All the other hens and roo went to roost at dust. She was just kind of wandering around rubbing her beak on the ground, etc. She is one of our least tame hens and I walked right up to her. She wouldn't let me pick her up but she let me herd her all the way back to the coop. She tried unsuccessfully to fly up to the roost. We put her up there. In the morning, she was still there after the others had got down. The next day She was walking funny. Like stumbling around. They stay in the coop during the day (the indoor/outdoor inclosed coop) so I checked on her at my lunch. She was up and around with the others. Today she was on the ground when I opened the coop, nesting in the corner. She stood up and fell down. I made sure she had water and food. On my lunch break nothing much had changed. I put her separate from the others and when I got home she was still on the ground. She seems sleepy. My DH got home and he picked her up to inspect her again. One thing we had not noticed is how LONG her toenails are! My gosh! Everyone elses toes are pretty short for digging/scratching I guess. Hers are so long. We trimmed them as much as we could but that didn't help her walk. She looks droopy, seems sleepy but doesn't seem to be in any pain. Any suggestions would be welcome. Thank you! Please don't bash me if I have done something wrong. We are relatively new to chickens and and we have had her since the beginning. Thank you.
