I'd recommend The Complete Carpet Python book by Nick Mutton and Justin Julander.

Or just Call Nick Mutton just make sure you have a lot of free time when you do  I would agree that jelly bean is majority coastal but she looks really small but its hard to gage how big she is by a picture...her eating habits will also slow her growth..and as for the Jag sib question in pure coastal jag sibs they tend to be alittle brighter then normal coastals but with crosses its usually just letting somebody know its not a pure sub species...its hard to tell what an animal is sometimes just by looking at it so its a good idea to get that information from the breeder because high precentage crosses will look very similar to non crossed animals...also another good place to look and ask questions is the Morelia pythons forums

I agree with Jason & Sonjia. The book, the forum & calling Nick.

I agree she looks like an integrade, & she may very well be a Jag sibling.

Is she housed with the Coastal male? I see them together in a couple of your pictures of her. If that's the case, that may be causing her stress to where she is refusing some meals. If they are housed together, I would recommend separating them, into their own enclosures.

I have an IJ that refuses to eat rats. I may end up feeding her mice her whole life, but if I have to, that's the way it goes, I guess. I would focus on feeding her what she will eat for now, then worry about transitioning her over later, after she has some size on her.

Just my .02

Yeah if this pic is any indication then they are housed together. You have got to get them seperated and I GUARANTEE you will see a difference.

they had only co-habbed for a short time before my move in December.  the rest of the pics were just for pics.  she lives on her own, and I still really don't see much of a difference.  she had been eating mice regularly, but then my adult mice went bad and I am awaiting shippment of the new batch.  she has been eating the rats lately, but I am not counting on her keeping up the transition.  

Thanks for the book suggestion.  I was hoping for something a little more affordable at the moment.  I also suck at talking on the phone with people I don't know, so that leaves me with the internet.  I will look up the forums.  :) 

What are the temps in her cage?

Don't worry Nick will do ALL the talking!!! Listen up because he is a great resource. Moreliapython.com or like Redding Reptile Breeders on FB. I know a few things about Carpets.

Snakes that don't eat much or regularily will be smaller than others their age.  Nutrients= growth after all. It is very difficult to guess what locale a carpet python as they're easily interbreedable and overall don't have too many drastic differences in traits. A wild jungle or poorly bred jungle can look like a coastal in color and pattern-- selective breeding has gotten jungles to be black/yellow. Unless there's documentation an integrade could be mixed with any subspecies, or be a pure and you couldn't tell based on looks. 

A jag sib has no genetic potential, its a normal with a fancy name. Some sibs have cooler patterns than others.

her ambient it is in the upper 70's, almost about 80.  her basking spot is in the mid-90's.  My temp gun got dropped in water, so right now I'm relying on gauges until the next show.  she's in a vision with flexwatt hooked to a rheostat.  There's a uvb that is on 12 hours a day hooked to timer.  i don't gauge humidity since the gauges are crappy, but she doesn't have shedding issues. 

Temps sound fine. What is the UVB for?
