I have a 12 week old chicken who has been limping. At first, I checked for any wounds, which there were none. Her foot looks great on the bottom and toes appear to be all straight, not broken. She is limping a little less now but still lifts that leg up like it hurts her. It now looks like it’s swollen but I’m not sure what could be causing it. I’ll attach some pictures. If anyone could help me out, and if you think it’s some form of infection, what I should give her. She still acts very healthy, runs around, and eats. Thank you! Middle toe in the right.
