Yesterday I noticed one of my chickens had a limp, so I picked him/her up and checked the bottom of the feet - no black scab, so that's good, I thought. Maybe it'll just clear up on its own. Fast forward to today and the limp is worse, and I think the hock joint on that leg may be starting to swell up. I'll have to try to get pictures tomorrow, but since the difference really isn't that noticeable, I don't think it'll help much. So my little chicken just has a worsening limp, and that's all I really know at this point. He/she can still get around and free range and keep up with the rest of the flock, so it's not really a big issue yet. I'd like to nip it in the bud before it gets worse, though. Does anyone have any idea what this might be, or am I still stuck in the 'wait and see' phase?
