We started with 200 adults, and left them alone for about 5 months. By then it looked like there were 5 times that, so then we started feeding off the wingless sub-adults. After another few months, a few winged breeders died off, so we got a new batch. We sometimes feed off 200 per day.
The best advice: keep them very warm! We keep the colony around 95 degrees F, this seems to prompt reproduction. Keep dry food and veggies available all the time. Instead of water - we use squashes; pumpkin; sweet potato; carrots and the ocassional fruit.
We keep the vertical egg flats (like our cricket set up), and ofen lay one flat on top with veggies. We keep a 100watt bulb on them during the day, then rely on the heatmat for night-time heat. I have heard that some folks keep the heat on them 24/7... but they seem to be breeding just fine for us.
Someone else will have to comment on the comparison between Discoids and Orange-heads as far as the reproductive numbers - we've never counted them.
Good luck!
