Sounds like it might be a hock injury. Did you feel the joints to determine if the joint is hot? That's usually a dead give away. I would just watch her. If you want to provide any kind of pain relief, blueberries are high in natural aspirin as is turmeric. They don't like the turmeric much though as it has a very strong flavor. Getting them to try blueberries can be a bit of a challenge due to the dark skins. I keep mine frozen and cut them in half or four, depending on the size. They will at least try them this way. Then they'll know what they are and unless the berry is large, you won't need to cut it up.I have a dom who has gone gimpy. I've done a cursory exam, and can't find any obvious issues. She holds her left leg close to her body through the hip and thigh. She is gimping around with minimal weight bearing, bearing a bit of weight through the hock and very loosely held claw. When I try to get her to grasp my finger in a tenodesis action, she does not, but then again, neither does she grasp with the other foot when I'm holding her. She comes out of the coop, and gimps around with the rest of the flock, she is eating, no obvious loss of conditioning... yet. She was up on the perch last night... sleeping alone on the lower perch. A bit of a concern, b/c it was in single digits last night. She laid an egg yesterday, after I noticed the limping. Will observe a couple of days. I've thought about moving her into a cat crate at night, but hate to restrict her movement. I'm sure getting up and down from perch is not a comfortable thing for her... Ideas???
