This afternoon when I went out to check on my girls after work, I noticed that Betsy was holding up one of her feet. When I went into the run, she would move around on it and put some weight on it, but she appeared to be limping. Now Betsy is the least friendly of my girls and she doesn't like to be touched, so it took a few tries for me to finally wrangle her and pick her up. While I was trying to catch her she would run on it just fine. When I did finally get her, I pulled up each foot and inspected each of them. There were no scratches/sores or anything stuck in them. They looked perfectly normally, other than a little dirty. I let her down and put out some scratch and she was standing and eating normally when I left. Anyone have any ideas?
