You could try wrapping her leg up in a Bandage or something like that to comfort her leg?
My chicken had the same issue however she healed after a few days.
hope that helps :)
I have 3 chickens and i am recently treating them from scaly leg mites, 2 of the chickens are getting much better and their legs are less scaly however the other chicken has seemed to have gotten worse. Her feet used to be only a little bit scaly so I treated them with Water, Oil and Vaseline...
My chicken is almost 3 years now and she has just come out of broodiness (however we don't have a rooster) but the main part is today she layed an egg but it had to shell, it looked like a balloon. I don't know whats wrong so any suggestions would be helpful!
