@Ilike4hornedchams,
I live in the Caribbean, on a small island called Curacao just off the coast of Venezuela, it's impossible to order feeders for my Cham, i have a fruit tree it's called a Kenepa Tree and i think the beetles eat the fruit from this tree so i started on 1 night.
I did some research on youtube and found this video
And i went right on with it.
But i tried it like almost everybody would with oatmeal bedding but my beetles died out without breeding so i went to try it with dirt.
As soon as i did it with dirt they went crazy.
