Yes, its no problem and in fact, it seems strange and odd that people think they do not get along. At least to me.
If you would just stop and think about it, You know, forget what you THINK you know and take a third party view of this.
There are no cubicules in nature, if kingsnakes ate other kingsnakes routinely, there were be no or very few kings out there. They HAVE to get along or they would not be in exsistance. How and why you ask.
I know I know, but but but kingsnakes, well I lived in New Orleans, and I am using that area because it envolves eastern type snake eating kings. By my house there was this abandoned old house, with tin and boards and all such. Of course it was covered in vines and all manner of plants. On spring days if it was not too hot, you could walk down the driveway(what was left of it) and see speckled kings all over, sometimes two or three together, if you flipped the tin or boards, you could find way more. Heck, there was also lots of ratsnakes, gardersnakes, canebrakes, milksnakes and blackracers there too.
The point is, I saw the specks consume other snakes, but never there own type. In fact, I have never found a kingsnake of the same species, in a kingsnake stomach. Oh don't get me wrong, I am sure, no, positive it happens, but WHY is the point.
So in the field, finding getulus kings together was common. Finding pyros and thayeri in numbers together was common. Ruthvens in dense colonies, common. Yet, in captivity, you cannot do that because they eat eachother. How odd.
When I was young, I did not know kings ate their own kind, so for the first 20 or so years and a mulitude of generations, I kept and bred kings in groups.(still do) What you say? GROUPS. Hey I did not know they were cannibils with bones in their noses.
As the years passed, I did find out if you were lax on your husbandry, you could strave them into eating eachother. But you really had to starve them.
I also found out that they bonded in both groups and pairs. That is, if given the choice, the same female would breed the same male, year after year. That is, IF GIVEN THE CHOICE. Seen it in captivity and see it in nature, ALL THE TIME.
It took years to figure out how they bonded in the first place. But after a little thought(which most REFUSE to do here) and some experiments, it was obvious.
When snakes hatch or lizards for that matter, they spent time in a chamber or nest. They normally stay there until they shed. During that time, they clump up, that is, they coil together. This occurs with rattlesnakes too, and they are not hatched. They are born. With rattlesnakes, the mother normally stays with the offspring until at LEAST after the first shed, and sometimes longer. I have seen this with pyros, but most egg layers are hard to view without interrupting the whole thing. Rattlesnakes are easy. A side note, once a friend found a pyro nest, with 6 gravid adults, 17 eggs, and a 8 hatchlings. In one spot. hmmmmmmmmmm that indicates a whole lot. What does this tell you?????? of course he destroyed that nest. I have seen the same thing, not so clearly, but with the same contents, you know, many gravid females in one spot with lots of different groups of hatchlings emerging at different times.
So why do they stay together? Why not just bolt like sea turtles. You know, hatch and boogy??????
My guess is, at the time of hatching, they form a scent bond with their clutchmates, and their mother or father(seen this only a very few times)
If you think about this, it makes lots and lots of sense. With no laws in snake society, its not a good idea to run about introducing yourself to your murderer, is it? So if all other kings eat you, what a rough world that would be. In fact, I find it odd that kingsnakes could grow up, if other kings ate them. Get it????? what easier food item then your own babies, heck, you even know where they are. Are you getting any of this? They must have some manner of a mechanism to maintain exsistance. I get it, they do not eat their own. They only eat the "others" Which means in snake talk, they consider any snake not in their own group, the others. Remember, they do not use genus and species, to animals its us, or them. End of that story.
So, onward and forward.
You can raise kings together without problem. But if you introduce another hatchling from another clutch, hmmmmmmmmmmm its most likely a food item, even with western kings.
But, so many of you have had kings eat eachother. Well that one is easy, your not all that smart(to their natural ways). Remember, no natural snake feeds of a schedule. They feed when they are hungry. And under normal conditions, they have NO problem finding food. Its kinda rare to find skinny wild snakes, and they have parasites too.
To make it a little clearer, they look for food as soon as they can swallow more. They do not wait four days after they poop, or eveyother wednesday, or twice a month or WHAT THE HECK, people are nuts. They eat when they are hungry, just like YOU. And just like you, they do not get hungry in the same about of time. Different then you, they can and do change their metabolism, so they can go long periods without food, or increase their metabolism and run in high gear to consume and digest food daily. They do this to take advantage of prey windows. You know, lots of seasonal nestlings of birds, rodents, eggs, young lizards, bursts of frogs, etc etc. You do know, they cannot wait a week or ten days between meals during a nesting season for their prey??? don't you. Nestlings do not WAIT, once they become adult and aware, the bloody things are hard to catch.
So yes, wild snakes have schedules, but nothing like what we normally give them. Soooooooooo the results we normally get are nothing like what they really should have.
So of course somewhere in here, I will answer your question. So heres the answer.
Yes, you can keep kings in groups. But you need to understand what kings/snakes are, and understand their needs.
So in order to do so, you should raise them from babies together(really helps but not exactly necessary) and two, do not strave the bloody things or they will eat eachother, just like most other animals including mice, rats, and people. Thanks for listening, hahahahahaha Cheers
