Snake Reproduction
"Reproduction:
Snakes produce offspring in 2 basic ways. The first involves development of the fertilized eggs within the body of the female. When the embryos are fully developed, the offspring are born, appearing like miniature adults. Boa constrictors, water and garter snakes, and rattlesnakes are live-bearing species...
The second method involves deposition of oblong, leathery-shelled eggs within the environment, where the eggs incubate.
At the completion of embryonic development, the eggs hatch, producing miniature adults.
Pythons and rat and milk snakes are egg layers, and are considered oviparous.
In either case, the newborn or newly hatched can fend for themselves and receive no parental nurturing.
Many snake species readily mate in captivity.
One mating may result in up to 3 clutches of eggs or 3 "litters" of live young. This is because sperm can be stored within the reproductive tract of the female after insemination.
The proper pairing of snakes according to age and sex is essential if reproduction in captivity is to be successful.
Sexing of snakes can be difficult because males generally resemble females....
The widely accepted method for sexing most snakes over 18 inches in length requires specialized sexing probes.
These elongated, blunt-tipped instruments are gently inserted into the vent and directed toward the tail. The probe penetrates only a short distance in females and a much longer distance in males. This procedure should only be attempted by experienced handlers.
Artificial Incubation of Snake Eggs
Artificial incubation of fertile snake eggs is quite easy.
A small amount of water is added to an empty Styrofoam picnic chest Then, a thick layer of peat moss, sphagnum moss, vermiculite, shredded newspaper, or paper towels is added. The eggs are carefully introduced into this medium. Slightly moistening the incubation material also helps prevent the eggs' drying out. Too much moisture, however, promotes formation of mold, which will destroy the eggs' contents.
The relative humidity required to incubate snake eggs falls within the range of 75-85F. ....
The ideal temperature range for most incubation lies between 78 and 84F.
The average incubation period for most snakes ranges between 55 and 60 days. "

Be aware that Incubation techniques can and do differ from breeder to breeder

it's not written in stone.
I would think that a triple clutching refered to in the above article would be exceedingly rare, but perhaps in some bloodlines...
Does anyone have any triple clutching Corns?
