Yellow Foot or Red Foot? Help please!

Okay last friday I bought my new Tort from a local person. They said it was a Red footed tort and they thought it was a boy but their friend said it was a male. When we bought it, I brought it back home and it saw my 2 3-toed hybrid Ornate box turts and made a head bobbing motion, So i figure its a male, but i would still like help because to me its undetermined if its a male of female. Also, the torts feet are red but yellow spots up and down the legs. So im lost, please help. Thank You!

take a look at the tip of it's nose. a redfoot will have one large prefrontal scale, while yellowfoots will have two prefrontal scales in parallel.
