My 4week old chick just developed a issue with her leg foot. Her middle toe is bent in odd way. Almost 90 degrees. When she walks the bad foot alwAys lands on good foot. Her leg shakes when she walks on bad leg. It appears bigger than good leg. She shows no signs of pain when u touch her leg or foot. But when she walks her right leg crosses the front on her body and ends up with bad foot on good one. Making next step difficult. Any ideas would be greatly appreciated.
