Dose anybody got some tips on raising New Zealands?

When I bought my black rabbit Susan the runnings label read mini rex.I know how to take care of mini rexes I've raised a couple litters. But Susan that was supposed to be a mini rex turned out to be a new Zealand,I think. And she had eight kits(babies). So far 5 of them are alive and they are only one день old.I'm not sure if Susan knows how to take care of them. I don't know how New Zealands take care of there young.
Please help I'll give Ты lots of props!!
