Food for Yabby juveniles

Hi

From previous posts I note that some readers have successfully breed yabbies
in an aquarium.
My question is "what should I feed the juveniles?"

The heavily berried mother is currently in a large tank, heated to 21C with
lots of aeration. The juveniles will have their yoke sack for about three
days, but then what will they want to eat?
Should I try to introduce daphnia, or will they be able to eat at small
pieces of carrot

Thanks

Laurence
