My thoughts are as follows.
You signed up here a year ago with almost zero knowledge about snakes. You have stated you continually research and study the habits of these animals, particularly this species.
But frequently, you come up with questions like this. Granted this is a discussion board and we are all here to help, you should be very aware that snakes don't eat weekly, don't eat bi-weekly and don't often even eat monthly in the wild. Excessively large prey items are not recommended.
In captivity, feeding should not be excessive, nor should it be overly frequent. Captive bred prey items are not the same as wild prey items. The increase in fat and decrease in exercise in captive bred prey makes it FAR more unhealthy in certain aspects than wild prey items.
Your last post was in regard to ferrets on Craig's List.
I LOVE your enthusiasm and I like your snakes. However I think you need to step back a tad and intelligently raise your animals for the long haul.
Take some time and enjoy what you have and don't be in a rush to grown a big snake or to breed anything.
I get concerned when I see folks that are new to the hobby start looking into breeding and acquiring more and more animals. There are VERY FEW long time retic owners posting here. It's possibly due to lack of interest in the social aspect of things, or its because people start up with these animals and eventually find out they are too much.
I think the moderator here, "BCR", is one of a few long time retic owners/breeders here that should be looked upon favorably when it comes to committed owners.
I'd say go with typical prey items that are not overly large. Rats and quail are fine, rabbits are also fine. Just think long term and don't at all think about breeding. There are far too many people producing these animals, and far too few that can care for them for the long haul amongst us.
Take this post as advice, and nothing more.
Feed your animals intelligently and look into longevity and you will have an enjoyable experience.
