My buff orpington is limping this morning. She is favoring her right leg and putting weight on her left side. She limps when she walks and also limped inside her nest box trying get comfortable (to lay her 10th egg). I had to put her inside her nest box and I took her out after she laid her egg. I then carried her out to the tractor with the other girls. She cannot scratch for bugs, but is instead hanging out at the feed bowl today. She is the top hen, so the other 2 pullets seem nervous and worried without her normal leadership. There are no signs of redness or swelling but I just don't know what happened. Most of all, will this limping go away or will it cause her to die? She is our favorite chicken (the one pictured in my avatar).
