Please see Part I of this article for notes on constructing a practical outdoor nesting area for Green Iguanas (Iguana iguana).
Nests with Underground Access
Some breeders (and commercial farms) prefer to provide an underground entranceway into the garbage can nest site (Please see Part I), which is more in keeping with the Green Iguana’s habit of constructing a nesting chamber at the end of a long tunnel.
This can be easily arranged by running a pipe from a hole in the buried portion of the can to the surface (please see Part I of this article for details on plastic garbage can set-up). Clay pipes are recommended, as they provide good traction….PVC might be too slick, especially at steep angles. Iguanas entering the pipe will excavate a nesting chamber at its end, within the can.
It is difficult to provide sufficient depth for a proper nest indoors, but some success has been had with earth-filled plastic garbage cans lain on their sides (use a square-sided rather than a round can, so that it does not roll about).
You can increase the available digging area by placing a rectangular can on its narrow side, so that the higher (wide) sides extend upwards. Place a step in front of the can to allow the female to reach the entrance hole, which should be cut in the upper portion of the lid. The lids of cans used in indoor cages should be secured onto the can with duct tape.
I’ll cover incubation and raising the young in future articles.
