only one question really:can you cover the beardie eggs with vermiculite untill they start to hatch?
If you can get your hands on a polysterine box thats you pretty much sorted. You make a cut near the top so the wire for the heat mat can go in with the lid still on properly, and then put little tubs in ( chinese food boxes or the ones you get crickets on) put the vermiculite in and make sure it stays moist. have fun :)
