Does my hen have arthritis? She limps quite a bit and likes to lay down a lot. When she walks, she looks so goofy... either she takes short little strides or almost looks like she is marching. She is about 4 years old and a silver laced wyandotte. I read around on here and saw it usually is a virus or maybe an infection in the bones? She got attacked by a dog maybe 6 months ago and had troubles walking for about a week. Could that be coming back?
