One of my hens (White Rock cross) has a funny gait! She started a "goose step" walk with her left leg only. She walks like she can't bend it. She hopped ALOT last week, but she manages to keep away from the roo, so I am not REALLY worried, but it is concerning. She has no problem with being picked up or me feeling the leg from stem to stern, so i am perplexed. Should I limit her "exercize" or just let it go but stay watchful. (BTW, we call her Limpy now) Any suggestions would be appreciated. Checked for bumble foot and other common ailments, no signs of injury. Could it have been the weight of the roo breeding her?
