I noticed this morning that one of my blue Australorp's is limping. She is not putting any weight on her left leg. I picked her up and touched her leg, and it didn't seem to bother her. I put her on the picnic table and her immediately laid down. I then put her on the ground to be with the other chickens and she hopped to the other chickens. Is there anything that I can do for her? I should mention, that she has a slight birth defect and had extremely short legs and her toes twist to the side.
