Hello Amartin7226,
It is great that you have not given up hope in breeding your snakes. After 5 tiems, most people would have frowned and never tryed again. People who never stop trying are not failures, because they are learning each mistake they make. You fail when you quit without a positive result from your past mistakes.
Ok... Now if you browse the internet or look at other snake books out there. You can find diagrams of incabaters made with a 10 gallon fish tank, 2 small bricks, a plastic container, and a fish tank heater. But I have learnd that if you do not want to invest into a hovabater. You can get a old broken fridge. and strip out it's guts and run a large heatpat into it and place it on the bottum and use rectangle plastic containers with Perlite in them. You will have no problem hatching your snakes.
Now just so I dont get to far ahead of myself... Let me tell you how to set up the plastic containers with your eggs.
I would fill the containers with about and inch or 2 with Perlite. Or enough so you can put the lid on the container without it touching the eggs. Then I poor and spray water onto the Perlite. I mix it while I am makeing it wet. When it is all damp, place it back into the Fridg and you are all set. When all her eggs are layed, just pick them up and put them into the container with the Perlite. Make sure you do not rotate the eggs. Put them into the cintainer the same direction they are when she layed them. After that all you have to do is put a thermomiter into the fridge. And moke sure you keep the temprature around 80* and no higher then 85*.
Then weight about 2-3 months and they will hatch. The peopel here tought me that I dont need to check on them every day or every other day. Each time you check on them you are changeing there temp and humidety. The nice part about useing a fridge is that with a small incabater, each time you open it all the heat has left the container. But with a fridge more of it stays inside.
I hope this helps. Search the internet for Fridg incabaters. Good luck.
By the way... If she is to young or not big enough, she will not have big litters or healthy eggs. Some people talk about hibernateing them. But I have never done that. I think this next year I will read up on it and see how it changes from my past 3 litters. A Book that alot of us cornsnake lovers fallow is a book called "The Cornsnake Manual" Get it! And read it from front to back. It is like the #1 cornsnake book out there. My next breeding project is going to be Gopher snakes, Indigo Snakes, and/or Red tailed boas.
