Sanity check

Are these normal looking legs or do I have a mite infestation? I have 15 hens that are just under a year old. They free range and sleep in coop. I clean the coop out every day, the floor of the coop is sand and I regularly sprinkle FSL or coop conditioner throughout the coop. None of the hens are acting differently, but I picked up the speckled Sussex and started to wonder about her legs. Snapped photos of her legs while standing and while holding her, along with another hen's legs. The Sussex has the "worst" looking legs of them all.
