Hen walking weird?

I have noticed in the past few days that my one hen, I really don't what kind I can't remember, she is white. Anyway since I have been treating all my hens and expecially my Roo for scaly leg mites this hen has started to walk like she is in the Nazi army. I believe it is called goosefoot marching? But anyway could this be from the treatment of scaly leg mites, which is just vaseoline on the legs and sevin dust 5% in the coup, or is it something different. She does not have any swelling on her feet, she doesn't even really look like she has scaly leg mites. I know they are contagious so I treat everyone. If anyone has any ideas that would be greatly appreciated. Thanks. I happen to think that this is the most awesome site for chickens. Everyone on here have always been very helpful and kind.
