My buff orpington is about 3 years old. She just recently started having trouble walking. Walks like she has arthiritis. She doesn't appear sick in any way. She is quite pigeon toed now also. Some of my other chickens are pecking at her and she is very anti social now. Does anyone know what this could be?
Here's some info about your chicken's problem. Hope it helps. It's an older thread, but the people are very knowledgable. Don't see this symptom posted often.
