Crawfish eggs are typically laid and fertilised in the burrow where they become attached to the swimmerets on the underside of the female's tail. The hatching period depends on temperature and usually takes about 3 weeks. ... When conditions force the crawfish to remain in the burrow, increased mortality can occur.

How many babies do crawdads have?

Generally, a female crayfish can hatch 400 to 1000 eggs at a time. But that doesn't mean you'll get 400 baby crayfishes. Some will not hatch. Some babies might die after getting hatched.

How do crayfish carry their babies?

Crayfish mate in the early spring and females carry the fertilized, developing eggs inside their bodies for 4 to 6 weeks. These developing eggs are then transferred to the outside of the female's body and glued via an adhesive called “glair” to the female's tail. The eggs then hatch by the end of spring.
