My one Barred Rock hen has started limping pretty bad. She did this about 4-6 weeks ago, no bumblefoot or apprent visual injury. She recovered on her own. She a normal, healthy 2 1/2 year old otherwsie. Eating pooping, laying. Goes up and down the ramp. She's in an urban flock. I can't feel any dislocated hip or? I don't bring her inside last time, just watched her closely and she recovered on her own. With our inside cat I don't want her inside and it's mild outside right now. Any ideas what this could be?
