Just for future info, rabbits can't move their offspring. They need returned to a nest with enough warmth and protection, mainly mother rabbit fur and some have used dryer lint to replace it, plus the ability to get out of it unassisted when ready. They are very very hard to hand raise partially because rabbit milk is very hard to replicate as they grow and wean, those that adjust to handfeeding often die when solids are introduced, so it's better to try putting them back. It only takes about 2 weeks before they are mobile and can return themselves to the nest area and survive without mom's fur. After that point if they have to be removed from the area they are much easier to feed because they can eat formula soaked items like pellets, oatmeal, or bread and avoid the difficulties of hand feeding.
