I'm going to be gone a vacation for 10 days. My enclosure if fully automated except for food. My temporary solution is to let a bunch of crickets loose in my chameleon's enclosure. But I've never done crickets. My guy usually eats dubia's and some BSF's but since they don't move much, he often...
This community is awesome and second only to Chameleon academy for accurate information. On the other hand, the Reddit cham community is horrible, just horrible. It would be like getting all your news from twitter.
Keep them very cool, but not refrigerator cool. After they turn black and hard, they will be hatching in several days. Unfortunately, since they don't move at that stage, they're not very appealing to chameleons.
Personally, I like glass over screen, but you need to really get the ventilation right and keep the air moving a bit so it doesn't get stagnant. Your uro enclosure is beautiful, but chameleons like branches (which you could add to your existing enclosure)
