I think the mom will eat them, but Im not an expert. Crayfish eat everything, so why wouldnt they eat their young?

tough call...id seperate them just in case though

do you have anything in with the crayfish? if not I would move mom

It's not Mom that you should worry about. Crayfish larvae are highly cannibalistic towards their siblings. Faster growing juvies will actively hunt down and eat their slower growing brothers and sisters. Size-grade separating and short interval feeding schedules can reduce (but not eliminate) the crays feeding upon each other. Most importantly, provide a calcium supplement for the crays molt. Larvae molt frequently in their initial growth spurt. A bird cage cuttlebone will provide the needed calcium. Without a supplement, the crays will go for each other to gain the calcium their systems need. Also, add a couple of drops of regular medicine cabinet iodine to aid in their molts.
