my advice. wait at least a week before any type of interaction. Then attempt to feed and let it settle for a couple days. The feeding in its cage over taking it out depends on the owner. in your case you have aspen I would recommend taking it out I use green sheets and Houston Press newspaper as my bedding. It used to be though that feeding in another tub, cage, or what ever kept cage aggression down because of what you said "...that way the snake don't think I am trying to feed it everytime" Well I handle all my snake on a daily basis so I am not opening the cage up everytime to feed. I think it is less stressful on the snake to feed in there cage, but again you have aspen bedding which can cause problems if ingested during feeding. Also it seems more natural to the snake because the snake is not going to go to another enviroment to eat and then come back to its home...
as far as moving the hid to feed. most of my snakes will come out of the hid once I open the cage and hang the rodent in at the door. if you stick to a schedule on feeding (which I recommend you do) you may be waiting for a ball python to come out of its hide to feed sometimes.
Though you really should wait for him to settle in for a week or so, a lot of owners don't, I did with all my snake except for my boa but that is because I wanted to get her to calm down because she was really aggressive. but she has never skipped a meal and has calmed down a lot over the past couple months I had her. when I got her you couldn't go a foot with out her hissing or striking it used to be glove up and to deal with her now I can just pick her up with no tention between her and I
