I'm actually feeding my first batch of dubias at the moment. Norman ate one in a cup right off the bat then seemed to lose interesting them, since they don't move around a whole lot in there. Since they seemed so inactive on their little egg crates, and I was too lazy to fish them out one at a time for a less than enthusiastic chameleon, today I just grabbed a small bit of egg carton (about 5 eggs worth) with maybe 20 or so nymph on it and stuck it amongst the leaves. Not one roach attempted to leave the egg carton either on the way to the cage nor once in the cage, but they did scurry from the top of the carton to the underside once they felt the cage light shining on them. All that sudden activity brought Norman, who happily picked them off one by one until the survivors made it to the underside, at which time I flipped it and the process continued. Once he was full I was able to simply retrieve the carton with its remaining roaches and put it back with the rest. I couldn't have been happier with the simplicity of the whole thing! Norman agrees!
