This hen has been broody and we are trying to break her. Buy yesturday we noticed she is hopping/limping on one leg. Today I check the 3 joints with no pulling away like it hurt ankle, knee, and hip. So got to thinking what about the bottom of the foot. So my wife held her and when I started to open her foot she went crazy not sure why so took a picture. Saw a small rough spot. I really have no clue, any thought
