I noticed my red leghorn hen was limping this morning and looking at her foot, it seemed swollen. Moreso on the back toe (don't know the technical name for it sorry), but her foot in general seemed pretty swollen too. I'm not sure if she stepped on something or what, but she doesn't want to put weight on it. I'm worried it's infected. I separated her from the rest of the flock but that's it so far. She's a year old and acting normally as of now. But because I freerange them I'm considering the possibility that she injured herself on something around the farm. Any ideas about what I should do? And what it could be? Please help!
