Not an emergency but a question

Okay, So I have Red sex link hens, they are about 8 months old. They're legs are yellow, but have spots of green on them, as if they are going to turn completely green over time, I am wondering if this is normal

I can try to get some later when I go home, but its hard because they free range, If I do get any it will probably be when they are roosting tonight.
They all still act normal and happy go lucky, I got them from tractor supply, so they could be a mix of something since they are just sex links.
