I looked these up a while a go but I'm quite new to chicken keeping and these didn't seem to be bothering her until now. She's one of a flock of 22 and she's the only one who seems to be staying inside most of the day. I went in yesterday and she was sitting on the floor but I don't know if she was just catching some sun there or not. I had a look at her feet and there seems to be something in there but it doesn't look specifically inflamed. Any insight would be great.
