Congrats on the opportunity and the gravid girl!

As others said it is ultimately up to you. Transporting a gravid female and eggs is doable, you just need to have something secure to travel with so things don't shift around. I'd say a big question is also how many snakes you have to take. 10 or so wouldn't be so hard, while 30+ would be too big of a hassle. As pointed out already, you'd really need someone you could trust. I've gone on trips for 5-6 weeks and during that time I had my brother to care for my 40+ snakes - I'm not sure I'd trust anyone else.

So answering those major questions should give you your answer:
- How many do you need to transport?
- Do you have someone you can trust with the lives of your reptiles?
- Is not being able to see them going to completely make you uncomfortable the entire time you're away?
- Is there a chance the job could be extended?
- Do you know someone that can incubate eggs and care for newborns, possibly sell them for you, or handle problem feeders?

Best of luck with whatever decision you make!
