The pullet with pale legs is indeed a Speckled Sussex, and the one with yellow legs is likely a Barnevelder judging by the double lacing. Though it could be a Dark Cornish judging by the comb.
Thanks everyone! I was thinking Barnevelder as well. So does anyone know much about this breed because I know nothing about them except that they're rare. Are they good layers? Good with kids? Skiddish? Thanks!
