Which incubation medium are you going to use? I use vermiculite that I get from my local home improvement store in the garden center. I am not as anal as other about the water to medium mix. I put the vermiculite in a container and microwave it to sterilize it. I then add enough water to soak the medium. I then pick up handfuls and squeeze out as much moisture as I can and use this as my incubation medium. This is not and exact science but it has worked for just about every creature I have hatched and at this point in my life has got to be nearing the thousands. How are you going to incubate them? I have a home made incubator with a herpstat thermostat controlling the temps. This is about all. Don't mess with the eggs once this process starts make sure the vermiculite stays moist throughout the entire process. Good luck and enjoy the wait. It seems to take forever. I just realized that you only asked about egg laying!! sorry, the above info may help anyway.
