Yellow spots on chicken's legs

[Mr Potatoes]

Hello! I was putting my chickens in tonight and I noticed a strange yellow spot on one of my hen's legs. I checked my other birds (all are hens) and I didn't see any other yellow spots. I have 5 Salmon Faverolles who are about 2 years old. Any advice would be welcomed! (I'll attach a picture of the spot).

but are there any other symptoms? Maybe it's just a stain from something....

could be a mark like how we get birthmarks or she might have gotten a stain such as from an egg

There's no other symptoms that I can notice, and she seems to be acting normal. I guess it might be a stain from a cracked egg yoke, but I haven't seen any cracked eggs around either.
