Clutch Size

For cornsnakes; what is you average clutch size? What are your biggest and smallest clutches? What is you average yearly production, and high and low average yearly production (double, triple clutch)?
 
Only one year of experience, breeding just one female, but here's my results:

1st clutch: 13 eggs; all fertile, all hatched

2nd clutch: 10 eggs; 8 fertile, 2 slugs; only 6 eggs hatched


I don't know of anyone that has had a cornsnake produce 3 clutches a year, though I may just never have heard of it.
 
I would say that a female corn that has good weight on her will usually double clutch and produce at least 30 eggs a year. I have had a couple of females produce over 50 in one year. Average clutch sizes are about 12 - 18 eggs. All female corns will not double clutch, but most will. I have never had a triple clutch from a Corn Snake.
 
The average clutch size is around 18-35 eggs. My female last spring is only under 2 yrs old, and is less then 2 inches wide. She layed 8 eggs and only four made it, her last clutch was only 4 eggs and they all died. Its different for every snake, you never know what your going to get. When you do succesfully breed them its really hard to sell them to pet shops or privite owners. Iv sold one to a pet shop out of four.
 
smallest clutch was a 1st time female amel-6 eggs and all hatched and survived
biggest clutch was from my sunglow motley femal-29 eggs 3 slugs and all but 2 hatchlings survived. Between about 12 clutches, on average I have about 18 eggs per clutch, and a 96% successful hatch rate. This is an average of all my clutches though, so it really depends on the snake.
 
I've had one year or breeding corns, and discounting the fact that the eggs all produced defective corns, here are my results:

1st time breeder female (normal het motley, amel, anery): 10 eggs first clutch... all lived to hatching, all ended up euthanized. Second clutch 1 slug, 1 egg that never developed veins even though it looked perfect in every other way, and three viable eggs.... one died near-full term, one was dead in the egg at hatching, and the third was euthanized.

1st time breeder female, very small to breed, anery stripe: 6 eggs and 6 slugs. One egg died early on, 5 went full term, 2 hatched, three were dead in the egg, all kinked, one is still with me only slightly kinked and with a huge appetite.

Proven breeder reverse okeetee: She laid 21 eggs exactly 39 days after being introduced to my male. I didn't even know she was gravid. In fact I was holding her when she laid her first egg! She laid 21 total, no slugs, never ate and died on the day they started to hatch. :( 1 ruptured in the first weeks of incubation, 2 ruptured a week before they were due to hatch, one I saved by putting a bandaide over the leaky spot. Of the 19 I saved 4 (the rest were euthanized) and only two of those are still with me.
 
Gosh Sasheena, that is so sad, you had a really bad 1st seasons breeding, I really hope it gets better for you next time. :)
 
If it doesn't get better, I'll just know that breeding cornsnakes is not for me! Ah well!

Next year three clutches.... two of the females from last year, and one proven breeder female... possibly a fourth clutch... and we'll see how they turn out.

Perhaps I've used up all my bad luck and all the rest of my clutches will be great from here on!
 
I see a lot of people talking about breeding corns that are two years old---I thought it was best to wait till they were 3 to avoid some of the problems that have been discussed here.

I mean, isn't it healthier for the corn if you dont let them breed at age two, but make them wait the extra year for them to gain size and mass? Just seems like a harsh thing to put them through if they're already small and not fully matured at 2 years of age.
