We use MistKing and love it! Works great! We have it set up over the cage and it seems to work better then having it in the cage. It leaves water droplets there all day long and our Chams now know it's always there and will go up and just drink from it.
They can get up to 2 inches but the baby Dubia (nymphs) would be perfect for them.

We got ours from there ^ the website has a lot of great info about them too! Hope this helps :)
We have had some chams that took us forever to name too :) We even named one then changed it once we got to know him and his personality haha what about Finn:D
Our Chams love eating Dubia and they are actually better for them then crickets :) Pretty easy to take care of too! We just keep ours in an empty fish tank with some egg cartons so they can hide. They like being in a dark humid area though. So they are kept in the water heater closet Haha seems...
That isn't true.
I would check out both Dez's video and Jann's Blog and be sure your laying bins are similar.
