Ok guys. I need some help feeding my 10 year old son's juvenile captive bred BP. Bought him at the local pet store 2 and 1/2 weeks ago. Pet store said he ate fuzzy mice twice when fed in a paper bag and they recommended I feed outside the enclosure in a bag or shoe box so the snake won't be prone to biting inside his enclosure. The day we picked the snake up was his normal feeding day at the store so they put him in a bag with a mouse for about 20 minutes before we left, but snake did not eat. Guy said not to worry since the snake was probably stressed since my son had just handled his new pet. Brought snake home, set up 20 gallon glass tank with 92 on hot side with UTH and red bulb heat lamp. Temp on cool side is 80 and humidity is 50 to 60% with hides on both sides and a water dish in middle. Substrate is reptibark. Also put in tree and plastic plants for added security. Did not handle snake and waited 3 days before placing snake in shoe box with live fuzzy mouse for 45 minutes with no luck. Waited another week and tried same with no luck. Waited a couple more days and placed f/t fuzzy mouse inside enclosure outside snake's hide and left overnight-still no luck. I've read not to handle snake until he begins eating but it's difficult with a 10 year old so he has held the snake for a couple of minutes twice in the past 2 and 1/2 weeks. Snake appears healthy and often moves around the tank flicking his tongue. My questions are:

-How long should I wait before trying to feed again?
-Should I feed live or dead?
-Should I feed outside the enclosure or inside?
-If I feed inside, can (should I) I leave a live fuzzy mouse inside the enclosure overnight as I've read that a mouse that small can't harm the snake?

Sorry this post is so long but I wanted to provide as many details as possible. My son already loves his new pet-he saved for months to buy it with his own money so I've got to get this thing to eat. Everything I read says not to panic but since it is a young snake and it's my son's pet, I guess you could say that I'm beginning to panic. Thanks in advance for any help or suggestions you can provide.
