In regards to sex determination in neonates, the only thing that I've heard of is the temp
relation to sex determination of turtles and tortoises. Light should have no bearing on sex
determination. As I stated before, Snake eggs are usually laid in the dark, deep in rock formations
where the temp and moisture are at a constant. If the eggs were to be laid where the light could be
seen, the survival of the clutch would be at risk as the exposure to the elements could cause a
drastic change to the egg and possible dehydration to the eggs. Basically the eggs would have no
protection at all and failure to reproduce in the wild kinda defeats the purpose of the reproduction
A rheostat (Dimmer switch) works well if used with a heat tape. Heat tape is used in the colder
regions of the country to wrap around pipes in the winter to avoid colder temperatures from freezing
the water pipes. One caution though, don't allow the tape to cross over itself as it could short out,
even though it has a plastic covering. Crossing over itself creates a hot spot on the tape therefore
causing a short out and, possibly, a fire may result.
One last thing that I didn't mention is that you should not rotate the eggs. In other words, if
an egg is laid on it's side the side of the egg that is facing up, should ALWAYS be left as it's
laid. Once an egg is laid the embryo has settled on the top of the yolk sack. Snake embryos are not
suspended by fibers like chicken embryos. A chicken egg can be rotated because these fibers holding
the chicken embryo don't allow the suffocation of the embryo by the yolk when the egg is rotated.
With snake eggs the the embryos are balanced on the top of the yolk. If the egg is turned or rotated
the embryo can slide off of the yolk and then become suffocated by the yolk. Nature has a way of
preventing this from happening by allowing the snake eggs to stick together and forming a cluster of
eggs making it harder for the eggs to change position therefore preventing the eggs from dying. I
hope that this is helpful . Bill
