I'm a new snake owner, ready to pick up my 1.0 spinner bp tomorrow from the breeder, and I have a couple of questions regarding the feeding of snakes in a separate tub/enclosure.

I just switched the substrate in my 10 gallon tank from Forest Floor to a mix of Komodo Coconut Terrain and Exo Terra Jungle Earth after dealing with some humidity issues (which were resolved when I changed to dried bedding). There's a label on the Jungle Earth bag that warns against feeding your snake within it's own enclosure due to risk of swallowing the substrate while it's eating it's prey (I will be feeding f/t rat pinkys, because that's the food item the breeder has started out with, so he's going to be already used to f/t; I live in Northern Europe where live prey feeding is illegal due to animal welfare laws).

My worry here is impaction and digestive problems if he happens to swallow some of the substrate while eating, how common or likely is it if you're using substrates like Reptibark, Coconut Terrain, Jungle Bark, etc? I was thinking about just getting a couple of plastic tubs and put newspaper or paper towels in there for a clean feed with no risk of impaction. I believe the breeder has previously kept him in a rack and has not fed him in a separate tub, I didn't want to keep a single snake in a tub so I bought a glass/display tank for him instead. I've been told he's a good eater (the breeder has fed him successfully 5 times) and I don't want to change his feeding response by stressing him out.

Is it better to feed him in his own tank and just make sure the rat is dry and won't get big pieces of substrate stuck on it, or would it just add stress for the baby if I take him out and feed in another tub? I would imagine feeding in a different enclosure would get him more used to a feeding schedule and he would learn when food is being offered, by associating the separate tub with prey. Wouldn't this potentially strengthen his feeding response even more, or does it really make any difference? I intend to feed him during the evenings. I have no problems feeding him in his tank, other than being worried about impaction.

What substrates do you guys use and how many of you feed your bp's in a different tub/enclosure? How big of a risk is it for snakes to swallow their substrate or bedding while eating? In the wild they obviously do end up getting some dirt etc into their system so I don't see it being that big of a deal, I'm just concerned because of the texture of the substrate I'm using.

If I do get him a feeding tub, how long should I wait before moving him back to his own enclosure so he won't stress too much and end up regurgitating his meal?
