Our Barred Rock has a slightly swollen joint in the hock? area. She is getting around slowly. She is eating, drinking and coming over for treats. She is 6weeks old. They have been in the coop for 2 weeks now. This is the 1st week outside in their yard. She limps when she walks. Poop is normal. Is there anything I should do for her or just watch her and make sure it isn't getting worse.
