I went out this morning to check on the girls and noticed one of my hens was limping. She was still energetic and making it around the yard fine, just slowly. I picked her up and checked for visible sores, injuries, discoloration on her leg/foot and found nothing. I left for work and decided to check on her when I got home. When I got home and realized she was still limping I decided to soak her leg a bit in epsom salt for a little while, which was recommended on a few other threads. Here's a video of her behavior this morning. Later this afternoon it was a bit different of a limp, seeming to be trouble bending and flexing the ankle or knee joint. She'll stop and just lay on the ground to peck around. any advice? should I confine her a bit and encourage her to rest with easy access to food and water? any other tips or treatment?
