Hi,
I think its great that you are doing research prior to breeding. I can tell you that I started breeding a few years ago and it has been a fantastic experience.
Contrary to what a lot of others will tell you, if done correctly it can be very rewarding.
I personally breed Panther Chameleons. They have much smaller clutches than Veileds and you should be able to find them homes much easier.
I would recommend starting with a nice pair and going that direction.
Believe it or not incubating has been the easiest part, other than the waiting. It can take you 6-12 months of incubation.
You need to think about the space needed, lighting, misting watering and supplements. Not to mention food. I am at 20,000+ crickets a month not including the other feeders.
This is just a brief overview. You are definitely at the right place for information. There are so many great members here who are more than happy to share what they have learned.
Baby chameleons are awesome. I could watch them for hours
Good luck and ask as many questions as you need.
Jason
