I've had a number of wild caught blood pythons and my experiences have run the range from "pretty poor" to "not so bad". Here is my run-down.
1. Dont buy WC's. I have sold every single one I ever bought for various reasons, but I know others have faired better. Since you have them we'll give it our best shot and you can learn from my mistakes.
2. Tuck them away in a warm cozy spot. Shred some newspapers lengthwise and give them hideboxes. Make sure their cage is good enough to house them for an extended period of time. You dont want to shuffle them around or have to pull them out every week to clean. Spot clean if possible.
3. External Parasite- Depending on who you got them from they may have ticks, mites and internal parasites. I might start with a small piece of No Pest Strip in their cages to keep mites/ticks from spreading. Even if you quarantine in another romm these little guys can travel fairly well. You dont want to get to aggressive here because they are stressed and too much insecticide wont do them any good at all. Another option is to place the NO Pest strips outside their cages to prevent any from exiting. Make sure nobody in the house has any issues with vapona and make sure you dont have any pets nearby. I'm not a real fan of No Pest but I'm less of a fan of mites. A second option, and one I have done with success, though many will say it probably isn't wise, is to use Harts flea spray you buy at Walmart. You can spray around the outside of the cage to contain any mites or ticks. Let it dry and air before putting the snakes near the dried chemical. I have also used it in adult snake bedding with great success. P.S. I am a molecular biologist and we could argue the evils of vapona and permethrins for an eon. I have carefully used both near neonate GTPs-adult bloods with no deliterious effects. Just be careful! You can get more aggressive later as they settle in.
4. Internal parasites-dont rush to pump them full of worm medication unless absolutely neccessary. They'll likely need worming later but for now just let them recover from their stressful ordeal. If they start to look lethargic and dehydrated and wont drink or eat for a fairly long period of time (they should drink within a few days of arriving, but they may not eat for several months, though some eat within a few weeks) get them to a vet. Sometimes the parasite load shifts as a result of stress and the snakes can get overwhelmed by the worms.
5. Patience - this is my biggest problem. I buy snakes I want to look at them and play with them. Dont. Just leave them be for several months. Let them get settled in and comfortable. Check on them every few days but just let them rest and recover. I started out by opening cages and checking on them. After a month or two I started talking to them and after another month or so I would put my hand on them while a talked to them. I didnt pick them up and I only took them out of the cage when absolutely necessary.
6. Attitude - my WCs have run the range from quite docile to really nasty. Even the nasty ones will calm down a little. Just be patient. If you got adult bloods and tehy dont have a little bit of a pissy attitude it might be cause for concern. Just keep a close eye on their color and vitality. If they slip get them to a really good vet and/or write one of us.
Their are several people on this list who have wrangled WC blood pythons and it is in your best interest to talk to as many of us as you can and learn from our experiences. I certainly dont have the magic formula and every scenario is different, but I have learned quite a lot through my failures.
Good luck
