I think they definitely have silkie in them, bc my girl has a similar crest, 5 toes, darker skin, and black silkied feathers. I heard the silkie gene is recessive so she might be a mix of two silkie crosses? Idk! At first she was larger then my other bantams as a chick, actually the same size as a paint silkie that was a week older than her. While she is still about the same size as her older flock sibling, the other bantams are catching up to her in size (especially my mottled cochin bantam). I highly recommend the bantam Easter egger from mypetchicken! Very intelligent, beautiful, and mostly friendly birds (just slightly standoffish). I have two in my flock, along with the mottled cochin bantam, my green queen bantam, a sultan, a millie fluer, a silkie, and 4 seramas (two of which are silkied).
