Scales a little raised...scaly leg mites?

[My Three Chicks]

Hi. I'm fairly new to chicken raising and this is my 1st time dealing with potential parasites. Can you look at my girls legs and tell me if you think this is scaly leg mites? The scales are a little raised. She's been holding eat leg a little more often. I've checked for bumblefoot and she doesn't have that. Not sure if holding up your leg more is a symptom of scaly mites but the scales are more raised than how I remember as well. Other 2 birds don't have the same raised scales. Wondering if I should start treatment. Thank you.

They don't look very raised to me but a slather of Vaseline won't hurt anything in case it's in the beginning stages.
