I've raised the florida blue crayfish a few times. The female will carry the eggs for about a month. When they hatch they will remain on the female for a while, but it's best to remove them becuase she will begin to eat them at this time. To remove them just hold her in the water and swish her around gently. The babies will be about .25 inches long and will eat flake food and just about anything else. They are not picky eaters. They will even eat each other when they have molted their exoskeleton and their bodies are still soft.
