Yay for detail! : ) I have a couple additional questions - how deep is the substate - can she burrow? And how are you offering her food? (On tongs, in / out of her tub, left in her cage overnight, etc.) What size tub is she in?

If the hot spot is 80 - 85F, what is the ambient? Wondering is a bump to say 87F of the hot spot could stimulate his appetite... overall, though, a week isn't long, and them being pretty strong ambush hunters, he may just need more time to adjust and feel comfortanle / secure.

My experience with Bloods is pretty limited, but I believe I recall reading that depending on the particular type of Blood Python, some are chunkier than others as babies. Might be something to look into to see if you can get a good feel for what is typical for yours.

As far as feeding attempts, I would wait a good week, and then try dangling a warmed prey from tongs. If that doesn't work, I'd place it in the front of the bin (away from the heat source) and leave it overnight. If she is hangung out in a hide, then you could try at the entrance, too. Sometimes babies are just really shy feeders. You could just clear an area or you can put down a plastic lid to lay the prey on so it's off the reptibark.

Also, if you haven't, I would make contact with the store to get some documentation going in case it is a health issue. 

I've been doing a lot of scouring on the web and looking at a lot of pics. Looking at the babies that breeders are posting (bloodpython.com has a lot of clear hatchling photos), babies of the same species/variety are chubby as a rul. Mine is chubbier than most snakes her size, but not so much for a blood, you know? 

As for the feeding thing, I have plenty tricks up my sleeve to try and coax her into feeding that I will be trying after I have left her be for a week. Thanks for the additional tips :) I know that if they are used to feeding on mice they will often not readily accept rats so I may offer her a mouse next time just to get something down her and ascertain whether it's outright refusal to eat or just pickiness over prey type. 

I'm still concerned about her scales though. I'm not turning up any solid info online. Most scale related issues seem to stem from humidity, but nowhere is telling me what to do about it as some places say t's a sign of too high a % and others say the total opposite. I've dried it out in there a bit as it was on the higher side of things initially, so I guess I'll see if it helps. I was hoping somebody in here might have some experience in this matter specifically ut in the meantime I will call the shop and run it by them and see what else I can find online. Thanks again Sonja! 

Called the shop just now and registered my concerns. Also asked a bit about how they were being kept. Quite differently to how I am keeping her now, so I am going to try and alter her tub so that she is closer to what she's used to and tweak it over time to get her to optimum condition. I have been told that she was being fed mice as opposed to rats so that is possibly a factor in her refusal and also that she was fed inside a paper bag at the store so I may try her that way as well. He didn't seem concerned about her scales.

I am probably worrying too much because I am new to blood babies and want to do right by her, but it can't hurt to be cautious and maybe a little over-observant, right?! :D

Give you baby a week of no contact at all...some do take a couple weeks to settle in...When trying to get them started feeding, well....they are not thrilled with your company...just put it in and go away, I fed at night, dropped it in, turn lights off and left.....sort of...I used a red light so I could watch at a distance without her seeing lol  Once my Blood was settled in she has no problem eating dinner while I have my dinner and watch her eat..lol  but at first, she wanted it dark and me out of sight.  Keep humidity at least 50%-60%.  I keep warm side at 84 degrees and ambient at 77-78 degreesI would continue offering her rats.  From the pic...she can take a rat pup easily....My girl is a little over 3 years old now and thriving.  Dont worry so much...Bloods are a hardy snake and once settled, very easy...

Thanks Lisa! Yeah, she can easily take the rat pup, she just didn't even register it! I will try her on another after a week or so, in the dark, on her own! Any thoughts on the skin thing?

Could be she is coming into shed...???  They don't give much in signs of moult coming on..but the scales feeling like loose...flappy...is one...then they just go dull..lol  can ya get me a belly shot of what you are seeing?  How old is she?

You don't want to tong feed a Blood really...Is better to just always drop it in and make sure you are not in line of strike when you do...you will see...lol

She could be. Loose/flappy is a good description. No colour change yet but she certainly could be coming up on a shed. I don't know when she last shed. Honestly, try as I might, I cannot get a photo that doesn't just look completely normal. It's more how it feels than how it looks? She's baby. I don't know her birth date but she can't be more than a few months old.

At 5 months old my girl was taking rat fuzzies every 10 days..now that we have reached Jumbo rats she is every 4-6 weeks...They like to eat and will become obese if you are not careful...lol  About how long is she?  How big around?

I'd say about 11-12" long and maybe 1" across her fattest point. The pics of ther above are a pretty accurate representation of her size :) I don't even have any tongs here yet so I've not tried tong feeding her. I hung the rat by its tail over the edge of her tub in her line of vision, wiggled it a bit and dropped it near her. She saw it but left it both times I tried. Thankfully my similar sized carpet and boa are both pigs so nothing goes to waste!

Yeah...pup good size...and I would drop it at opposite end of where shes at..don't worry..give her time to settle and watch for her to look like she has panty hose on..that is exactly how my girl looks when in moult..lol. 

That's great. Thank you! Definitely helped ease my mind! It's funny... with every new type of snake that I keep, new things pop up that are normal for one species and not for another. Even after 12 years keeping reptiles, there are still so many surprises and so much to learn! I love it and I'm happy to be a part of a community of such knowledgeable, helpful people :)

And when she dies shed...watch...and time it..right in the middle of one shed to next she will get in her dish a lot...don't be afraid to give her avdish she can get in and cover herself..they like to get in water..  My girl has a large cat litter box to get in...and that's too small now...

That's great to know. Thanks. Would explain why she's been in and out of her water a lot!
