I would say mini-lop cross, and leave it at that. And yes, she's a beautiful little Magpie.
That's still magpie. It becomes harlequin when there are three colours, i.e. with brown too.
There is no such thing as a 'normal lop', there's the mini, dwarf, english, french, german and cashmere lop. I'd just call the babies lop crosses, if you call them mini lops then people will expect them to stay very small which may not be the case
its grey, white and black, is that still magpie, does it have to have brown to be harliguin, not seen any brown yet, but who knows ha its eyes keep going from brown to blue ha
