we have a young chicken less than a year old with really swollen legs. to start with we thought it was scaly leg but they're not flaking and pictures we've looked at of scaly leg don't look anything like whats wrong with our chickens legs. She's in a hutch with 2 other chickens and neither of them are showing any signs of the same thing and are in perfect health. the legs are swollen like a water balloon with a slightly green tinge to them. Has any one got any idea what might be wrong?? thank you so much for any help you can give.
