I noticed in the coop today that one of my girls was limping on her left leg. I picked her up and held her on her back like a baby in my arms (luckily she loves this). I checked both feet for injuries, swelling, discoloration etc. and found none. Then I checked her knees for movement and those felt ok; the left was tighter than the right. The main thing I noticed is that her left thigh is swollen and felt warmer than the right. I didn't see any external signs of injury. She is molting so I thought maybe she was uncomfortable. The limp is so bad that at times it looks like she might fall over. She's less than two years old and one of my best layers. I don't want any of my hens to hurt! Has anyone else seen this? Since I didn't see any immediate sign of injury I just sat with her in the coop. I let her fall asleep in my arms for a bit. I hate worrying about my girls!
