Mine only eats a couple bugs a day now so I just hand feed. When he was young I cup fed and let out a few at a time in the cage and he would wipe them out right away. Alot of people say to feed 15-20 bugs a day when young but I'm a believer of growing slower to prevent any mbd issues. From 2-6...
Go get a few braches from outside that can work for the vertical climbing spots and use those exo vines for horizontal climbing. I just use twist ties to tie all of my branches. It may seem alot for the exo vines but they are worth it and you really don't need that many.
Don't be sad theres no way possible he died because of you after only 3 days. I only have one and wish I could get more but my snakes are taking up room for my future cham cages. Maybe I should just sell them...
