For a while now one of our Jersey Giants, Helga, has had a great deal of trouble walking-- she hobbles as she would if she had arthritis (for all I know, she might-- I know that breed is rather prone to knee/hip injuries because of their weight). If we call the flock for food, she will break into a lumbering run, but usually she tries not to walk at all, and it's clearly painful when she does. She tends to stay sitting when she can. Today I examined her legs to see if I could see any signs of leg mites or anything, as I noticed her leg scales were turning white. She flinched when I touched the backs of her legs, but she really drew back when I touched her knees. Her knees seem puffy and bumpy as well. Anybody have any ideas? I've tried researching it with no luck. Thanks so much!
