Like I said you do what you want and what you feel comfortable with. What I'm sharing in this post is both my opinion and other peoples opinions I have gathered from researching the topic and reading other members opinions here.
Feeding in a separate enclosure requires you to move the snake after it has been fed, this causes unnecessary stress and a bp should be left alone 48hrs after it eats bc you don't want to cause a regurge and the stress of moving after fed could cause this. Also the snake is going to only associate the separate cage for feeding time only which can cause you to get bit especially bc the snake will be in feeding mode with the smell of rodent in the air and you have to reach back in there to return it to its main cage. In the snakes actual enclosure you have less risk of being bit bc it associates it own cage for more then just feeding, it sleeps, poops, slithers, hides, etc in there and plus you won't be reaching back in after it had meal bc your suppose to wait at least 48hrs and after that time has past the smell of rodent will be gone unless it was a messy feeding. I hear most of the time people saying that its possible for the snake to swallow substrate if fed in regular enclosure and yes this is true but a snake can pass a little, think about it they digest a rodent bones and all with no problem. If your worried about the snake eating substrate you can always lay some paper towels down before feeding. I'm sure there's more but that's all I can think about right now. Like I said do what you think is best. I'm just giving you insight on the side of people who feed in regular enclosure.
