That is most likely a bacterial arthritis, such as MS or staph, not gout in my opinion. The toes appear normal while the ankle joints are very enlarged. Unfortunately very few people get this diagnosed, unless they get a necropsy after death.Here is the photo from that link. (this is not my chicken) I think the OP was asking about gout. I think Eggsessive was in the conversation. It looks like a Speckled Sussex
The post is from 2014 and it seems the OP has not been on BYC since 2015
i will try to fix the link
