Cut a hole in the lid large enough for the female to get in and out easily, but small enough to keep humidity in the lay box. Write the female's name on the box. Never share boxes between females. If you reuse the box next year, soak in a bleach solution, rinse, soak in an ammonia solution (never mix the two!!) and then rinse very thoroughly. If the female poops in the box, remove the poo immediately. It is very important to not contaminate the eggs. In fact, I wash my hands thoroughly before doing any handling of the lay boxes or egg containers.
