I noticed today that my barred rock was laying in the corner all puffed up (it's getting a little colder here in middle TN) but she looked as though she was breathing really slowly and deeply. When she tried to come my way she was limping really badly. I also noticed a small bruise like spot on her ankle when I picked her up? I' posted the image below of her foot. I have a video of her limp, but I'm not sure how to post it. Any advice on what could be wrong and how to help her would be greatly appreciated!
