Toby,
I have seen this at a lot of shows. I think it is a new fad going on, as it appears that people think, " wow, she wants to breed, so it must be ok." Well, I would have to differ with that opinion.
Just because something CAN or has the ability, it doesn't always make it right:
Drug addicts WANT to do drugs.
Overeaters WANT to eat too much.
So with that being said, I have talked with many breeders over the years and most would feel the same way as I do: Too many are breeding snakes at too early of an age or too small. I am talking mainly about kings, milks, and corns. The snakes are not requesting to be bred at 18 months or 2 years or at 22 inches. And if they produce eggs, so what? Like you used as your example in another post, if an 11 year old has her period, it still doesn't mean she is ready for sex.
Do people have clutches of eggs hatch from breeders too small? Yep. Are all the babies sick at birth? Nope, but I have seen very, very small babies from parents that were not what I would consider old or big enough. I have seen babies that did fine as well. Is breeding early always failsafe? In my opinion, absolutely not. To me, it is too much of a risk, so why bother until the snake is really at a good, maximum size?
If that cal king you purchased was 22 inches and bred at that length, then there is no excuse for that. IMO, that is way too small. I do have some experience in this as well, as I bred a cal king once that was about that same size, and she did not fare well and did not make it. This was more of an experiment, and I had heard that it could be done. Well, my snake didn't make it. The eggs were so stinking big that it made me realize that me allowing that to happen was a big mistake.
But it isn't just that example that I go by. You see a lot of snakes at these shows that are being sold as proven breeders that flat out show a snake that was put through what I call the Jon Bonet syndrome: The owner didn't let the snake have a childhood and made her act like an adult before she was completely mature, in both years and physical makeup. You can always tell the snakes that were sped fed and bred too young usually. A lot of times, they have no neck, have a stumpy appearance, and their girth is twice as round as one that was not sped fed and forced to grow too quick.
When I bred snakes, back in the nineties, it was common to think and believe that a cal king should be bred at 3 years old and about 3 feet in length. Well, I stuck to that with my other snakes and enjoyed many huge clutches of healthy eggs and healthy babies. I can't even remember an egg going bad. I am in no way patting my back at all, but just using that as an example of waiting till the snake is bigger than these two feet long snakes I have seen and known about. I would have my adult cal kings grow to well over four feet, produce 12-14 eggs and the babies were in great condition and size.
And when you breed snakes, wouldn't this be a summary of your goals somewhat?:
1. I want to have my adult snakes in their most prime condition to be able to breed and what is best for them is my number one goal.
2. I want to have my baby snakes to hatch and be the healthiest they can be.
Why can't people wait until their cal kings are that big? It can only take 3 years. They grow fast, and I have heard about some breeding at 18 months. I still highly disagree with that, but that is just my opinion.
I feel that those that breed snakes too young and too quick are doing that out of selfishness, plain and simple. What other reason is there? This is not to raise tempers, but to just simply state the obvious. They could wait until their female cal kings are older and longer, but they just simply do not want to. It is exciting to breed and to see what your snakes will produce. There is nothing wrong with that. But why not wait a little longer to have better results, not stunt the female's growth, produce bigger babies, and the life expectancy of the snake to be at its' very longest? Isn't that part of caring for your animals to begin with? That way, your hobby and/or business does better in the long run?
This was all my opinion and if some differ, then so be it. We can differ in good conscience and agree to disagree. Thanks for reading.
Take care!
Billy
