Follow the previous poster's excellent advice on where to find vermiculite and incubators. You might try looking in the yellow pages under 'farm equip' or 'farm supplies'. Depends on where you live - if you live in 'the big city'...farm supply stores may be hard to find. I own a Hovabator which is a very inexpensive incubator used to hatch chicken or other poultry eggs..which is why we are telling you to check farm equipment stores. These work fine for reptile eggs. I would suggest that you:
1. get vermiculite quickly
2. visit deerfernfarms or http://www.kingsnake.com/uromastyx/..check 'breeding and brumation' to get temps and humidity advice.
Note:
Most of the websites will tell you things like 2 parts vermiculite to 1 part water by weight. Which is all great if you have a gram scale. If not, a VERY ROUGH rule of thumb is 2 cups of vermiculite to 1 tablespoon of water.
3. Once you get your eggs into vermiculite you might try setting them on top of the fridge or on a warm appliance until you get an incubator. Be very careful with temps - if you don't already have one get a cheap, digital thermometer from Radio Shack so you can be sure of your temps. Until you get an incubator you could always point a 60 watt light bulb at your egg container and fool around with the distance until you get close to the right temps. This is a horrible suggestion but it might work in a pinch. You'll have to watch your temps over several hours to make sure that they don't continue to rise. If you are really desperate, most pet stores sell devices that are kinda like a thermostat and can control one heat source...like a light bulb. You might try that. Good luck.
