Like everyone else has said, definately wait about a week. I picked up a 3 month old Hoggie also and she fed the first day. Tried feeding the next week and found out she was in shed and didn't take the 2nd feeding. If she doesn't take a feeding after waiting a week, check your Hog's eyes for cloudyness. I find it harder to tell if a boa is shedding compared to ball pythons, until you start seeing them go blue. Just a possibility considering your Hoggie is just as young as mine.
