1 amberlink with green legs, Roo?

[Shellyb]

I bought 3 amberlink sexed pullets and now they are almost 3 weeks to guess and one of them has greenish feet, the others have pinkish. Could this be a roo or is it just a gene different since they are mixes? Thanks

Could you post pictures? that would help people guess better. Sandy
