I have a roach colony too that is doing great, but I have only one of my five dragons that will eat them. Even my gecko isn't eating the babies. So I'm hoping to eventually get the other 4 dragons eating them, as I know they're very nutritious & have alot more meat than supers. I gut load the supers nightly with what greens my dragons haven't eaten during the day, they seem to like it, also add in veggies like squash, they love that. So that's why I find them an easy staple to give my gang & they really love them. I give them silkies & I've found hornworms being sold nearby, so that's the next treat. My gang are very healthy & have good weights, so I'm pleased with the result. I also get them always from the same source, and they're gut loaded at the store I get them from, too.
