Not Hebs. They look like Norfolk Horn crosses - black heads and legs, but hard to say without seeing their actual size and fleece type. NH are larger than Hebs. Cross-bred Hebs nearly always have white lambs as they are a black recessive breed, but I am not sure of the genetics of Norfolk Horn. The faces are far 'coarser' or bigger than primitives with what looks like a big Roman nose, and from the photo it looks as if the fleece is a single coat, whereas Hebs have a double coat with the top layer around 7" long.
