Hi Adam,
Since there is some interest in feeding "roaches"...
I will jump in and relay our experiences with them as food for the chams.
First... we have tried 3 kinds of roaches: orange heads; lobster; and mad hissers.
First and foremost - the flying thing is a big deterrant. Even if you manage to get them into the cham's enclosure before they fly off into the house - they run and hide under anything in the cage (plants; flower pot; etc.) Once the bug is hidden it's "out of sight, out of mind" (we had one mad hisser that remained hidden for months until we finally found it)
The roaches come out at night when the chams are sleeping to feed, and it is harder than heck to find them without tearing up the enclosure.
Next - containment of the roaches. We used large storage tubs with screened lids for all the roaches. Since the mad hissers can even climb glass - you have to use vaseline or "Bug Barricade" to keep them contained. The vaseline is a mess, and even though "Bug Barricade" is great - it is hard to find and expensive.
Now to feeding to the chams - only appropriately sized roaches can be fed. We keep many sizes of chameleons (from stumptails to melleri) and figured this would be "no big deal". Wrong - we ended up with way too many adults, and no one to feed them to. Hence, we started giving them away for new colony starting. Finally, after keeping them for over 2 years, we decided to stop keeping them, and sold the colony of mad hissers (containing over 250 adults).
The chams may or may not take to eating roaches too. Before getting a colony, I recommend trying a few juvenile roaches to see if your chams will eat them. Not all do. Even though we had 20-30 adult panthers, not all would eat them - and usually only the males. The same thing with the veiled - usually only our big males would eat them - and then only maybe one or two per week.
This made it more trouble than it was worth. We now offer crickets; superworms; silkworms; moths - and waxworms as treats. This is a lot easier, trust me - and we have over 200 mouths to feed at any given time.
Hope this gives you some insight
