Leghorns have yellow legs also...he has the white in his face, which is typical of Leghorn males...especially those with large white earlobes. He could be a mix. In all honesty....the hatchery has "random" pens where breeder birds are put until they are needed. Sometimes...they gather these eggs...for some RANDOM reason? And then sometimes...a male gets in with another pen of females and well..you know the rest.
