I found a decent way to get the crickets to hatch. I've been having issues with keeping the soil moist. The eggs would dry out, adding water would drown them, etc. So, I did something different.
I took a standard small margarine container, 7.5 ounce size that comes in doubles, went and roughed up the outside and inside with some sandpaper, and added some semi sandy soil from outside. Then, I got some old fish air tubing and put that down to the bottom. Anytime the soil looks like it's getting a bit dry, I feel out a 12CC syringe, plug it into the tube and inject the water. The bottom stays wet and the moisture is drawn up to the top. So far, I'm getting some baby crickets.
Additionally, if you're feeling nice, you can give your crickets treats. I've found that they absolutely love oranges. I'll also give them the dried out baby food that my gecko leaves which gives them a treat, but it's also filled with calcium and vitamins from the supplements. This unfortunately does cause fruit flies, but I don't notice any in my room since I have a tight mesh lid on the tank.
Best suggestion I can give is this: experiment, because happy healthy feeders mean happy, healthy reptiles.
