Today I went down to the coop to give my chickens a little bit of bread and I noticed my Rhode Island Red refused to walk on her left leg. She was hoping all around on her right leg, and she refused to eat the bread(she would KILL for bread so thats not like her). I also cleaned her foot off to see if something was stuck or cut, but I didn't notice anything odd. I'm not sure if she's eating but I saw her drinking. Am I overreacting will it heal on its own? Should I take her to the vet or put a home-made splint on it?
