Hi Ethan, I always offer my snakes food on feeding day whether they are in the shedding process or not. If they choose to refuse that's fine, so long as I have offered!
With a 60% humidity your snake ought to shed out fine unless the humidity was off in the place you got him from. In that case, this shed might not be the greatest but the next one will be!
Please read this sticky on the shedding process and issues and solutions with incomplete sheds: http://www.ball-pythons.net/forums/s...ad.php?t=43403
Congrats on the first shed!!
