Hmm...looks like I am contacting the breeder I got them from a year ago. They have light feathers on their legs and white legs as well as white skin, so I never once questioned it. Kind of scared to post my non-pea combed full blooded Wyandottes on this site now. No two chickens are the same any way. I don't believe there's a possibility that they are mixed. When we got them she had Marans (black copper, blue copper, cuckoo, and splash ) , Wyandottes (Silver lace, gold lace, splash), silkies (black, white, blue, buff, partridge), and cochins(buff, black and blue).i have two blue cochins, the two Marans, and Silver lace Wyandottes from her. I had previously gotten silkies but coyotes got my last rooster. So I may be wrong but I am just not seeing it as mixed.
