Rubbermaid shoeboxes, with numerous small drilled vent holes around the upper side walls are fine. Perches, the diameter of their girth, are placed an inch or two above the floor. PVC, plastic, and well-cured polyurethane coated bamboo, or wooden dowels, are all easy to clean and will not grow mold. An easy way to set up the perch system in a Rubbermaid container is to set four perches up in a tick tack toe fashion. The ends of one set of parallel perches rest on the inner flange portion of the container, at about the perfect height.
High humidity is always important before and during subsequent shedding cycles.
Keep temperatures in the low 80s. A rack system, with dimmed heat cable under the back of the shoe boxes, is ideal for whole clutches. After the initial shed, the substrate can be changed to paper. Rarely you may get a clutch where all, or most babies will eat at the first trial. In recent years I have had much better success in feeding trials by day than at night.
