We use a lid from a dog food container that we beveled out a small "dip" for the eggs to sit on and then a very small hole to shine the light source through. We currently use a flashlight and it works great! We use it for our leopard Gecko eggs mostly, but since we have 46 Veiled Chameleon eggs in the incubator, we have used it on them as well and it works wonders. We have only done it to the Chameleon eggs a few times and used a different egg each time. We are hoping our eggs hatch out in October, but it could be as late as January!! They were laid April 1st.......what a kick!
