Little Black Chickies - Lorps? Giants?

[helmstead]

These 4 all have more white than I would expect on a black star, and are quite a bit larger than the black chicks (that look like sexlinks I've hatched here).

Is there any way to tell between Lorps and Giants or will I just have to see how big they get?
