thanks for the help. I took the picture myself and the legs are definitely gray. I live in Spain, does that affect the chicken's breed? Thanks.
Spain also has leghorns with yellow legs. Europe Leghorns usually have bigger combs than U.S Leghorns.
Those legs though......
I have dark brown leghorns, and it is hard to get good yellow legs on them...but they are never GREY.
Yours looks like a light brown leghorn except for those legs.......... I would maybe try to see what other breeds come in that color but with gray legs? Bit of a puzzle there.
